• proxy software to relay email

  - by Registered User

  My some software applications need to relay emails to my email account. The only way they can do it via connecting to localhost which relays mail on behalf of application. I have forgotten the name of such a software it is a Debian/Ubuntu environment. Can any one let me know the name of such an proxy software which relays mail to your local SMTP server on behalf of application I will need to enter username password also in this setting because the mail server needs authentication.

• Wireless network relay?

  - by IPX Ares

  Is there hardware (links would be great) that can connect to the wireless internet already in my house and provide hard links to other hardware? Basically the problem is that my basement is not wired up to let me hook up my cable modem. I have some electronics that do not have wireless and need a LAN wire. Is there something I could plug in downstairs to act as a relay hub?

• Tools for Remote Desktop with Relay feature

  - by Stan

  Is there good tool that can do same thing as windows 'mstsc' and also has some features, like save different session info, so don't need to remember difference IP/ID/pwd. Thanks. EDIT: Since I can't directly RDP to remote hosts, instead, I have to RDP to a terminal server and RDP from their to my destination. Is there client that can relay my connection from local and pass through the terminal to the real destination?

• Server is sending SPAM but it's not an open relay

  - by alexandernst

  I have a problem with Dovecot + Postfix. My server is sending SPAM from the local user "dovecot", but my server is not configured as an open relay (mails can be sent without auth-ing only from localhost). Also, nobody except me, has SSH access to the server. How can I find what exactly is triggering all those SPAM mails? How can I get something like a backtrace that shows what exactly happened the moments before a SPAM email got in the queue of postfix? Regards

• Weird vps server issue

  - by anon-user0

  I have an unmanaged linux vps Ubuntu 11.10 (Oneiric Ocelot). I have LNMP installed. Also php-fpm php-apc, varnish, memcache. I have (or rather had) several live sites on it. under normal load the server uses ~700 mb memory. But since last night its using only 20mb~ memory and a lot of the services seems to be down (according to htop) I only see nginx working and mysql starts up and goes does every few minutes on a loop. Here are some information on the server that might help you help me: root@server:~# uname -a Linux server 2.6.18-308.el5.028stab099.3 #1 SMP Wed Mar 7 15:56:00 MSK 2012 i686 i686 i386 GNU/Linux - root@server:~# ifconfig -a lo Link encap:Local Loopback LOOPBACK MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.2 P-t-P:127.0.0.2 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:12515 errors:0 dropped:0 overruns:0 frame:0 TX packets:9541 errors:0 dropped:1 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:7191214 (7.1 MB) TX bytes:536726 (536.7 KB) venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:176.31.158.78 P-t-P:176.31.158.78 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 - root@server:~# netstat -l Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 *:http-alt *:* LISTEN tcp 0 0 *:ssh *:* LISTEN tcp6 0 0 [::]:http-alt [::]:* LISTEN tcp6 0 0 [::]:ssh [::]:* LISTEN Active UNIX domain sockets (only servers) Proto RefCnt Flags Type State I-Node Path unix 2 [ ACC ] STREAM LISTENING 9307368 @/com/ubuntu/upstart - htop: http://i.stack.imgur.com/NHKYX.png EDIT: Stressed. mind was not working adding log: root@server:~# less /var/log/syslog Jun 27 05:27:42 server syslogd 1.5.0#6ubuntu1: restart.

• Zimbra MTA settings

  - by user192702

  Hi have some questions for Zimbra v8.0.6GA. Under Configure - MTA - Network, I'm seeing a few settings and am not very clear what to do with them. Web mail MTA Host name Is this for delivering local mail only (ie not for external mails)? According to this link, it says the following. That's a mouthful but what is "composed messages"? Is this for a multi server deployment where the Postfix server for Zimbra isn't installed on the same box that as the rest of the servers? Webmail MTA is used by the Zimbra server for composed messages and must be the location of the Postfix server in the Zimbra MTA. Relay MTA for external delivery My understanding after reading the doc is that if my ISP doesn't force me to relay outgoing mails through them, and I have enabled DNS lookup, I can leave this blank? Inbound SMTP host name Sorry I know this is explained as "If your MX records point to a spam-relay or any other external non-Zimbra server, enter the name of that server in the Inbound SMTP host name field." but I'm not following. Can someone provide an example? MTA Trusted Networks The admin doc says "To set up MTA trusted networks on a per server basis, make sure that MTA trusted networks have been set up as global settings and then go the Configure Servers MTA page and in the MTA Trusted Networks field enter the trusted network addresses for the server." However I see out of the box it has default networks setup for the server whereas on a global level it's blank. Does this mean there is a bug with the install software and I have to copy the setting from the server to the global setting?

• Tor : Stuck at Connecting to Relay Directory

  i have never ever worked with tor before. the company where i work allows us to have access to any site we wish. nonetheless as of the the beginning of this month, they installed a proxy server to filter which sites can be accessed and which ones cant. the filter isnt only on URLS, but IPS as well, even hexa IPS wont work. so after some research, i decided to use tor, the first day i installed it, everything went smooth and i was accessing any website i wish. just 2day, everything stopped. i try 2 start vidalia, it gets stuck at Connecting to Relay Directory. i work on windows 7 platform.

• DHCP Relay V DHCP Local Cisco v 3com

  - by DefSol

  Howdy, I have a client who has a WAN with 7 sites. At one site in particular, randomly about 4-5 clients do not get an IP address. The local gateway is a cisco 871 and relay's to a windows server in a Data Center running a valid scope for the subnet. If I put in a cisco 1800 and configure a dhcp scope (disabling the scope on the server) all clients get an ip address and everything is right with the world. The Wan providing keeps saying it's a local issue although we can work around with the 1800. The provider says a 3Com switch is at fault and the 1800 does not have a local switch, and because the 871 does, means the internal switching will receive a different uplink policy. The 3Com is the only managed switch in the subnet. Any ideas greatly appreciated. Reuben

• Yahoo flagging mail as spam when using relay server

  I'm using Postfix to relay mail from my site to my mail server. Mail is received properly at my Gmail and Hotmail accounts - only Yahoo is the problem. The Yahoo mail headers state: Received-SPF: none (mta1133.mail.mud.yahoo.com: domain of [email protected] does not designate permitted sender hosts) In contrast, the Gmail headers state: Received-SPF: pass (google.com: domain of [email protected] designates 74.50.xxx.xxx as permitted sender) client-ip=74.50.xxx.xxx; Reverse DNS is set up correctly, as is my SPF record and domainkeys/dkim (both domainkeys and dkim show pass(ok) in the Yahoo mail headers).

• Reject recipient in postfix mail relay

  - by galets

  I have about 3 knows email addresses in my domain, which don't exist and to which a lot of spam is sent. Some of this spam is pretty heavy, and I'm wasting a lot of traffic on it, so I don't want to even receive emails if their destination is one of those 3 addresses. Since I know that the users don't exist I would like postfix to reject emails during RCPT TO: negotiation. Basically, all I want is to update some config with those 3 addresses, and every email sent to them must fail to come in. I want to stress out following: postfix works as a relay for domain, there is no local users postfix has no knowledge about validity of other emails within domain, so it cannot simply reject unknown recipients

• postfix relay access denied from some IPs

  - by Caballero

  This is driving me nuts. I have Postfix/Dovecot set up on Centos 6 VPS for my emails. I can send and receive emails without any problems on my outlook (home broadband), on my Android phone (3G connection), however when I set up exactly the same email account on Outlook at my friends house I'm getting bouncebacks when I'm trying to send email (receiving works fine): 554 5.7.1 : Relay access denied Now if it wasn't working at all I'd understand, but why is it working on several internet connections, but not everywhere? Can someone shed some light on this? Where should I look for the problem?

• How to correctly relay TCP traffic between sockets?

  - by flukes1

  I'm trying to write some Python code that will establish an invisible relay between two TCP sockets. My current technique is to set up two threads, each one reading and subsequently writing 1kb of data at a time in a particular direction (i.e. 1 thread for A to B, 1 thread for B to A). This works for some applications and protocols, but it isn't foolproof - sometimes particular applications will behave differently when running through this Python-based relay. Some even crash. I think that this is because when I finish performing a read on socket A, the program running there considers its data to have already arrived at B, when in fact I - the devious man in the middle - have yet to send it to B. In a situation where B isn't ready to receive the data (whereby send() blocks for a while), we are now in a state where A believes it has successfully sent data to B, yet I am still holding the data, waiting for the send() call to execute. I think this is the cause of the difference in behaviour that I've found in some applications, while using my current relaying code. Have I missed something, or does that sound correct? If so, my real question is: is there a way around this problem? Is it possible to only read from socket A when we know that B is ready to receive data? Or is there another technique that I can use to establish a truly 'invisible' two-way relay between [already open & established] TCP sockets?

• Configure Postfix to send/relay emails Gmail (smtp.gmail.com) via port 587

  - by tom smith

  Hi. Using Centos 5.4, with Postfix. I can do a mail [email protected] subject: blah test . Cc: and the msg gets sent to gmail, but it resides in the spam folder, which is to be expected. My goal is to be able to generate email msgs, and to have them appear in the regular Inbox! As I understand Postfix/Gmail, it's possible to configure Postfix to send/relay mail via the authenticated/valid user using port 587, which would no longer have the mail be seen as spam. I've tried a number of parameters based on different sites/articles from the 'net, with no luck. Some of the articles, actually seem to conflict with other articles! I've also looked over the stacflow postings on this, but i'm still missing something... Also talked to a few people on IRC (Centos/Postfix) and still have questions.. So, i'm turning to Serverfault, once again! If there's someone who's managed to accomplish this, would you mind posting your main.cf, sasl-passwd, and any other conf files that you use to get this working! If I can review your config files, I can hopefully see where I've screwed up, and figure out how to correct the issue. Thanks for reading this, and any help/pointers you provide! ps, If there is a stackflow posting that speaks to this that I may have missed, feel free to point it out to me! -tom

• Exchange SBS 2003 server stopped receiving mail over the weekend, senders getting "Relay access deni

  - by Charlie W.

  Firstly, I should say that I know my way around Windows very well, I don't really know the first thing about Exchange. I am trying to support a user that is running an SBS2003 Server with Exchange. Over the weekend, everyone sending something to any of his addresses gets an error message like the following: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <[email protected]>: Relay access denied (state 14). ----- Original message ----- Received: by 10.114.18.7 with SMTP id 7mr5572745war.127.1275423472120; Tue, 01 Jun 2010 13:17:52 -0700 (PDT) MIME-Version: 1.0 Sender: [email protected] Received: by 10.143.10.15 with HTTP; Tue, 1 Jun 2010 13:17:32 -0700 (PDT) From: My Name <[email protected]> Date: Tue, 1 Jun 2010 15:17:32 -0500 X-Google-Sender-Auth: XiPrP8Em_6Eb94EH9m84nJVGvCY Message-ID: <[email protected]> Subject: TEST To: Client <[email protected]> Content-Type: multipart/alternative; boundary=001636b1484ffe72470487fdaa5b There are a host of errors in the Application log, but nothing that leaps out at me as being obvious.

• IPv6 Addresses causing Exchange Relay whitelists to fail

  - by makerofthings7

  Several of our new Exchange servers are failing to relay messages because it is communicating over IPv6 and not matching any receive connector I previously set up. I'm not sure how we are using IP6 since we only have a IPv4 network and we are routing across subnets. I discovered this by typing helo in from the source to the server that is confused by my IP6 address. I saw the IPv6 message and the custom message I gave this receive connector. (connectors with more permission have a different helo) 220 HUB01 client helo asdf 250 HUB01.nfp.com Hello [fe80::cd8:6087:7b1e:99d4%11] More info about my environment: I have two dedicated Exchange forests each with a distinct purpose. They have no trust and only communicate by SMTP. They both share the same DNS infrastructure via stub zones. What are my options? This is my guess, but I'm no IPv6 expert so I don't know which one is the best option Disable IPv6 Add the IPv6 address to the whitelist (isn't that IP dynamic?) Tell Exchange to use IPv4 instead Figure out why we are using IPv6 instead of IP4

• Setting up Relays in Windows

  - by Auditor

  I'm trying to setup a pivoting relay with netcat on Windows, replicating a scenario easily possible by using pipes in Linux. Assume machine A can route to machine B and machine B can route to machine C. If machine A needs to route to machine C, we can setup a relay on machine B which can pivot data back and forth for us using command redirectors and spl filetype pipe. Assume: machine C has nc -nlvp 3306 -e cmd.exe machine A has nc -nlvp 80 IF machine B was Linux we could have done mkfifo pipe nc -nv 127.0.0.1 80 0<pipe | nc -nv 127.0.0.1 3306 1>pipe so on machine B if we do nc -nv 127.0.0.1 80 0<&4 | nc -nv 127.0.0.1 3306 1>&4 Per this site, I should be able to achieve what I can with Linux, but unfortunately it is not working.

• Asterisk relay between multiple subnets

  - by immoune

  I wonder what's the best way to go when you have phones on multiple networks which are not directly reachable. I have 3 networks 10.3.x.x 10.6.x.x 10.17.x.x My asterisk server resides on the 10.3.0.5 IP. The machines from the 10.6 and 10.17 networks are routed here through VPN tunnels. At this point we don't talk about NAT anywhere on the network just pure routing. Since the 10.3.0.5 PBX has routes back to all the subnet's it has no problem to communicate with softphones/hardphones from these ranges. The problem comes from that Asterisk (as far as I understand) only responsible for the SIP communication part not the Audio/Video transmission which is in P2P fashion done between the devices. So although a client using sipdroid from 10.6.x.x is able to connect to the pbx (10.3.0.5) and dial a bria client on the 10.17.x.x network once the phone rings out and the call establishes no audio will be transmitted simply because it has no way to directly connect there. For this there are multiple solutions described in this text: http://msdn.microsoft.com/en-us/library/ee480411%28v=winembedded.60%29.aspx What I would prefer is to keep these networks segregated as they are now. What would be the best solution? Is it possible to actually relay through all the audio/video information through the Asterisk server? That would be the best in my case, I using Astlinux there which has a lot of other parts. Thanks

• 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)
