  • Override the bounce recipient address in exim4

    - by jerhinesmith
    I have a small app that allows a user to share an item by generating an email to a supplied email address. We set the "from" and "reply to" values to be the sender's address, so that when the email reaches the recipient, it appears to have come from the sender. This works wonderfully except when an email gets bounced. Currently, on bounces, exim attempts to redeliver the message periodically while simultaneously sending error emails back to the sender. I'd rather have those emails basically routed to an empty mailbox somewhere as there's nothing really that the sender can do about it. I found some documentation on bounced emails here: http://www.exim.org/exim-html-4.67/doc/html/spec_html/ch46.html and it claims that "Exim sends a message to the original sender, or to an alternative configured address.", but it doesn't say exactly how to configure an alternative address. Ideas?

  • Exim log and send all mail for a given domain through another server

    - by Josh
    I administer a handful of shared web hosting servers. Recently, Yahoo has been deprioritizing/greylising all email sent from these servers. I am getting the dereaded 421 4.7.0 [TS02] Messages from my.ip.address temporarily deferred message from Yahoo and their postmaster has been unresponsive. I am unable to find any way to set up a feedback loop like AOL has for my IP address -- I did find a way to set up a feedback loop for a given domain, but we host hundreds of domains, and don't have the time to set up that many feedback loops. So what I'd like to do is twofold: Configure Exim to send all email destined to an @yahoo.com address to a relay, a new server which has an IP that yahoo is not blocking. Configure Exim (or maybe the relay) to log all emails sent to @yahoo.com, so I can review them and, in case one of my uses is violating ToS and sending SPAM to yahoo users, take the appropriate action. How could I accomplish these? Or, does anyone have any other advice for how to get mail to flow through Yahoo and ensure that any email generating complaints is brought to my attention? (For what it's worth, these servers are not listed on any major blacklists)

  • VMWare Network bug in multiple VMWare Workstation versions if using a hardcoded IP address

    - by onyxruby
    I'm having a very tricky problem with some of my VM sessions being unable to reach the Internet or even ping the gateway. I have just set up a new VM Workstation (7) on a W2K8 64bit server (I'll be converting to ESXI 4 once I can find a decent book on it, so for the meanwhile I use workstation). I have imported a number of VM's and setup some new ones on the server.In short the problem with some of the VM's being unable to reach the Internet is that they can't reach the gateway. I've looking at a number of things and can pretty safely rule out the following: Switch, Router, DHCP Server, DNS, Client IP configuration, Routes and typos. The problem is that some of the new clients cannot reach the gateway if their IP address is hardcoded, they can't even ping it by IP address. That rules out DNS and DHCP. Now, if I allow them to get their IP address by DHCP they can reach the gateway and Internet without issue. The interesting thing on this, is that this behavior occurs even if I leave the DNS information hardcoded under TCP/IP settings. It doesn't work unless the IP and gateway are handed out by DHCP even though the same information IP info is being used by the host. Fundamentally from the standpoint of the clients, they are trying to reach the exact same gateway using the exact same IP information regardless of whether they are hardcoded or assigned by DHCP. Here's an example of one client. IP Address 192.168.7.66 - Subnet Mask 255.255.255.0 - Gateway 192.168.7.254 - DNS1 192.168.7.44 - DNS2 192.168.7.254. The issue occurs across six different microsoft operating systems, Windows 7 and Windows 2008 variants all have the issue. My W2K3, XP, Vista and W98 clients all work without issue with hardcoded IP addresses. I have tried things like rearranging the DNS order, flushing DNS and so on. It's not a routing or switch issue as the clients can work just fine if they get their IP by DHCP. It's not a paramater issue as the exact same paramaters are handed out by DHCP as I plug in by hand. It's not a DNS issue as clients cant reach other clients even with IP addresses only. I have run a tracert to the gateway by IP address and it times out on the very first hop before failing on hop3 with destination host unreachable. If I get the IP address by DHCP the tracert finds the gateway (and Internet) without issue. I have read a few other posts online in forums talking about this problem randomly occuring over the years in other VM versions as well, so I suspect some kind of long standing bug. Does anyone have any ideas on this? Is it possibly a bug with Windows 7 and W2K clients under VM?

  • Routing based on source address in Windows Server 2008 R2

    - by rocku
    Hi, I'm implementing a direct routing load balanced solution using Windows Server 2008 R2 as back-end server. I've configured a loopback interface with the external IP address. This works, I am receiving packets with the external IP address and respond to them appropriately. However our infrastructure requires that traffic which is being load-balanced should go through a different gateway then any other traffic originating from the server, ie. updates etc. So basicly I need to route packets based on source address (external IP) to another gateway. The built-in Windows 'route' command allows routing based on destination address only. I've tried setting a default gateway on the loopback interface and mangled with weak/strong host send/receive parameters on the interfaces, however this didn't work. Is there any way around this, possibly using third party tools?

  • subdomain on another ip address

    - by pixeline
    hello, my main domain (domain.com) sits on a server with ip address 1. I need to have a subdomain (forum.domain.com) point to a server with ip address 2. Both servers are hosted at iWeb, so i have a cPanel interface to manage them, but i can't find the right way to do that. I tried a .htaccess redirection, which works, but the visible address in the browser changes too. Any help on how to do that would be appreciated. Thank you

  • Assign fixed IP address via DHCP by DNS lookup

    - by Janoszen
    Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

  • ipv6 port 445 does not accept the request from a global type address

    - by blacktea
    I want to scan the port 445 in windows server 2003, but my scanner only have one type ipv6 address which is global not link-local. When I do this,I find that I can't find port 445 open. But I use the command "netstat -an" to assure the port 445 is listening. Finally I find this confusing phenomenon: 1.when I set a link-local ddress in my scanner, then it will work in scanning port 445. 2.when I only set a global address in my scanner, it doed not work. This means if a host with a link-local address use socket to send a syn packet to the port 445 in server 2003, it will receive a ack packet. But if with a global address it will receive a rst packet. Thus, I can't scan the port 445 in server 2003 with a global address. I need to know why? Can anybody help? And I use the netsh-firewall to check the exception and netsh-interface-ipv6 to turn off the firewall on the specific interface. Still can't establish the connection with port 445, do you have any ideal about this ?

  • Is it possible to rent an IP address to mask the server real IP address?

    - by net-girl
    A customer would like to lease an IP address and point it to a dedicated web server with the intention of "masking" the server's IP address so it would be difficult to tell where the site is hosted. I found a company that leases IP addresses here: http://www.webhostingtalk.com/showthread.php?t=1191688 Is this even possible? Can they rent an IP address from a 3rd party in order to hide the server's IP address? Update: My client will be hosting a government leaks site and is trying to become Raid-Proof similar to what the pirate bay did: http://torrentfreak.com/pirate-bay-moves-to-the-cloud-becomes-raid-proof-121017/ Only that I'm worried about using a reverse proxy because of the latency it could cause having the app servers hosted in one data center and the load balancer/reverse proxy in other and also having to pay twice for bandwidth.

  • network endpoint accessible via hostname only, not address?

    - by Dustin Getz
    someone told me that this piece of network hardware (NAS) has a security setting such that it can only be accessed by hostname, not by IP address. I don't understand, as I thought DNS resolved the hostname to an address on the connecting client's side, then at protocol level always used the raw address, so how can this 'security' measure be possible?

    We have several websites (with several public IP addresses) running on a web server. In IIS, the IP address are internal IP addresses (192.168.xxx.xxx). How do I figure out which public IP address matches which internal IP address? My goal is to change some public IP addresses. The particular web server is running IIS 6 on a Windows 2003 Server. Thanks, in advance, for your help!

  • Setting up a static IP address (public) in Ubuntu

    - by ycseattle
    I have a business class internet connection and need to setup a static ip address for a machine. I did a search online and only find how to setup static local ip addresses (like 192.168..). I tried the same technique, and only setup the ip address and netmask, but after restart networking the computer could not connect to the outside world. This is what I did: 1) edit /etc/network/interfaces iface eth0 inet static address 173.10.xxx.xx netmask 255.255.255.252 2) edit /etc/resolv.conf search wp.comcast.net nameserver xx.xx.xx.xxx nameserver xx.xx.xx.xxx 3) restart network sudo /etc/init.d/networking restart Now the last step didn't report error, ifconfig shows the ip address was set, but this server cannot connect to outside world, ping google.com and reports "unknown host google.com". Any ideas?

  • Configure IIS to rewrite IP Address to Site Name

    - by Bath Man
    So i've started my first web site from home, and I'm trying to get it up and running and google crawlable and the like, but I can't seem to figure out how to have my site name returned in the address bar instead of my IP address. I've purchased a domain name for my site on Godaddy and then set it to redirect to my site. When you type in the domain name, you get redirected to http://0.0.0.0/default.aspx (not my real IP obviously), and that stays in the user's address bar. In order to fix that temporarily, I've set up masking on Go Daddy which keeps the URL in the address bar, but just shows my website in a frame. This is fine for users visiting the site, however any kind of automated robot such as GoogleBot cannot discover my content because of the frame. I've looked into ISAPI filters and server-site-rewriting, and the like... but I just can't quite figure out how to do what I need it to do. Any simple suggestions or links would be appreciated.

  • Httpd restart "Address already in use" error

    I have an .rpm, which I created. In its %post part, I do some stuff, and in the end of this script, i call service httpd restart.

  • Postfix with relayhost - relay access denied for bounces

    - by Alex
    I have set up a Postfix Mailserver, outgoing mail is being sent through a smarthost/relayhost which requires authentification. That works great, internal clients can send to foreign recipients though this relayhost. However, when an external mail for a local, non-existent user arrives at the server, postfix tries to send a non-delivery notification to the sender. This mail is also sent through the relayhost obviously, but it fails with error 554 5.7.1 : Relay access denied This gets logged to the mail.log: Nov 9 10:26:42 mail postfix/local[5051]: 6568CC1383: to=<[email protected]>, relay=local, delay=0.13, delays=0.02/0.02/0/0.09, dsn=5.1.1, status=bounced (unknown user: "test") Nov 9 10:26:42 mail postfix/cleanup[5045]: 85DF9BFECD: message-id=<[email protected]> Nov 9 10:26:42 mail postfix/qmgr[4912]: 85DF9BFECD: from=<>, size=3066, nrcpt=1 (queue active) Nov 9 10:26:42 mail postfix/bounce[5052]: 6568CC1383: sender non-delivery notification: 85DF9BFECD Nov 9 10:26:42 mail postfix/qmgr[4912]: 6568CC1383: removed Nov 9 10:26:43 mail postfix/smtp[5053]: 85DF9BFECD: to=<[email protected]>, relay=mail.provider.com[168.84.25.111]:587, delay=0.48, delays=0.02/0.01/0.26/0.18, dsn=5.7.1, status=bounced (host mail.provider.com[168.84.25.111] said: 554 5.7.1 <[email protected]>: Relay access denied (in reply to RCPT TO command)) Nov 9 10:26:43 mail postfix/qmgr[4912]: 85DF9BFECD: removed According to this error, I suppose that postfix does not login at the relayhost when sending those bounces. Why? Normal outgoing mail works just fine. This is how my main.cf looks like: http://pastebin.com/Uu1Dryxy And of course /etc/postfix/sasl_password contains the correct credentials for the relayhost. Thanks in advance!

  • Transferring domains when registered owner's email address is incorrect

    - by www.jacob-
    Years ago I registered some domains using a now expired university email address. The other contact details for the registered owner (postal address and phone number) are still correct. In order to change/update the email address, the registrar wants to charge £20 a domain. I would like to transfer the domains away from the current registrar. I can unlock the domains and generate an auth code. However, I cannot authorise the transfer by email as any emails sent to the registered owner's address will bounce. This seems to rule out most registrars I have tried. Are there any ways to transfer these domains without paying the £20 fee to update the registered owner's details?

  • Access Google Apps Global Address List from Thunderbird

    - by Roy
    We're considering using Google Apps as groupware, with our Mac and Linux users (and likely a few of the Windows users as well) accessing mail and calendar using Thunderbird with Lightning. We seem to have worked out most features, but have not found a way to access Global Address List. Is there a way to sync the Global Address List to Thunderbird? Update: The Zindus addon as suggested by @superuser, does not have support for Global Address List from Google Apps (it does however support GAL from a Zimbra server)

  • Assign fixed IP address via DHCP by DNS lookup

    - by Janoszen
    Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.
