  • Sendmail to local domain ignoring MX records (part 2)

    - by FractalizeR
    Hello. I have the exact problem, like in this post: http://serverfault.com/questions/25068/sendmail-to-local-domain-ignoring-mx-records I am also using email provider like GMail For Your Domain (which stores your mail and manages it). I am sending mail from my server directly, but receiving mail is done via Yandex (email provider). Since the server hosts forum, I prefer to send mail directly from it because using another mail provider can slow things. Also, when I send 300.000 emails to my subscribers, email provider will surely block me thinking I send spam. My DNS zone now is: ; ; GSMFORUM.RU ; $TTL 1H gsmforum.ru. SOA ns1.hc.ru. support.hc.ru. ( 2009122268 ; Serial 1H ; Refresh 30M ; Retry 1W ; Expire 1H ) ; Minimum gsmforum.ru. NS ns1.hc.ru. gsmforum.ru. NS ns2.hc.ru. @ A 79.174.68.223 *.gsmforum.ru. CNAME @ ns1 A 79.174.68.223 ns2 A 79.174.68.224 @ MX 10 mx.yandex.ru. mail CNAME domain.mail.yandex.net. yamail-xxxxxxxxx CNAME mail.yandex.ru. Server hostname is server.gsmforum.ru. May be this is the cause? Can someone explain the reason of the matter (the rules that make sendmail consider domain to be local)? Can I easily change *.gsmforum.ru. CNAME @ into *.gsmforum.ru. A 79.174.68.224 to solve this problem? [root@server ~]# cat /etc/mail/local-host-names localhost localhost.localdomain This server hosts gsmforum.ru so I cannot put it into another domain like David Mackintosh suggests. Putting domain in mailertable doesn't solve the problem also. sendmail -bt still shows, that address is local. DontProbeInterfaces is also set to true at sendmail config.

  • ID protect vs Nominet domain privacy

    - by Antony Scott
    I currently use 1and1 as my domain registrar but am considering using another company in order to get a 10 year registration. I've noticed a couple of companys are charging for privacy, but Ive done it myself with my domain via the Nominet website. Is there a difference? The only one I can see is that my name is listed in the WHOIS information, whereas with these ID protect services my name is withheld.

  • Multiple network connections on a Windows 2008 domain controller (private network for NAS)

    - by Sysadminicus
    I have a Windows 2008 server connecting to an iSCSI target on an OpenSolaris box (yay ZFS!). I'd like to create a private network between the 2 boxes that is totally separate of my Windows domain. What is the best way to configure the additional network adapter on the Windows machine so it doesn't think the new subnet is part of the Windows domain? I want to make sure Windows doesn't magically start spewing active directory communications over the private wire and that it doesn't start poisoning the DNS with IPs from the private network.

  • Reset Windows user domain password

    - by Jan Zich
    Is there a way to reset a user domain password remotely without login to a remote desktop to the domain controller? I could not find any MMC plugin in non-server Windows (Window 7 Ultimate in this case) to manage Active Directory which is understandable.

  • nginx www.domain.com vs domain.com virtualhost

    - by m33lky
    I have an http block where I include virtual hosts for the different domains hosted on the same server. For each virtual host I do: listen domain.com:80; Now, domain2.com works fine. However, when I do www.domain2.com it shows the page for domain1.com! How to properly configure nginx? Does this have something to do whether www is a CNAME or an A record? Update: It looks like you can do the following: listen 80; server_name domain.com www.domain.com;

  • I want to add a Quality Assurance domain. How do I handle DNS servers?

    - by Tim
    I'm advising a large client on how to isolate their dev and testing from their production. They already have one domain, lets say xyz.net with the active directory domain as "XYZ01". I want to add second domain say QAxyz.net and make its active directory domain "QA01" All development and QA servers would be moved to the QAxyz.net domain, the machines would be part of the QA01 domain. Note: Some of these servers will have the same name as the production servers for testing purposes. I believe we would have separate DNS servers for each domain. If I am logged into the QA01 domain, to access the production domain I would qualify my access like so: \PRODSERVER.xyz.net login: XYZ01\username Do I need to add a forwarder to my QAxyz.net DNS server so that it can see xyz.net? Would I need to do the same to the xyz.net DNS server to see QAxyz.net? I don't know how to advise them in this. Does anyone have any other recommendations to isolationg a QA domain? Many Thanks in advance! Tim

  • Domain authentication used for kerberos based authentication of users on my server

    - by J G
    Suppose a user process has authenticated itself against domain's directory server via kerberos, and then attempts opens a network socket to my server application. My server application has a white-list of users from the domain directory server. How does my server app authenticate the user from the directory based on this socket opening attempt? (To keep things simple - let's say my server is written in Java, and the directory server is Active Directory) EDIT My question is about how the client asks for an authentication token.

  • Pros and Cons of using internal or external domain name for Active Directory

    - by MadBoy
    I was always thought to use internal domain name (company.local or company.corp) for Active Directory instead of (company.com or company.pl). Recently we were thinking that by using external domain name we can get some advantages for stuff like certificates for Exchange, Sharepoint and alike where internal and external name would be exactly the same making it unnecessary to buy special certificates. What are advantages and disadvantages for both? What could be potential problem when doing so and what could be a big advantage?

    - by Jonathan Rioux
    I would like to know how can I accomplish the following: When I join a workstation (with Windows 7) in the domain, I want that computer to be put into a specific OU.

Or can I set a rule like if the computers has Windows 7, put that computer into this specific OU.

  • Make website reachable through domain?

    - by Msmit1993
    I'm learning to use IIS 7 but I don't understand how I can make my website available through a domain. I have a domain as example I will call it www.test.com I have made a website in IIS, running on port 80 and can be viewed by typing the IP of the server in the address bar of my browser. So if I type www.test.com in the address bar how do I make my IIS website show up, without a redirect of course, I don't want users to see the IP in the address bar.
