I'm currently in the process of bringing email inhouse at my company. We have a domain through GoDaddy which is pointed (Not MX Settings, however) to our one static IP address. I followed the steps on www.linuxmail.info including the tests. I'm running Postfix and Dovecot. I can send email to outside addresses i.e. Gmail and Yahoo, but cannot receive from the outside (only internal). My hostname is mail.<mycompany>.local, with SMTP and POP3 open on both the outside and linux firewalls.

What do I need to set my MX Settings on GoDaddy and what, if anything, else do I need to do in Linux?

Thank you,

First make an A record:

mail.domain.com. IN A <ipaddress of the mx server>

Then make the MX record:

domain.com. IN MX 30 mail.domain.com.

You may want to change the hostname of that server though, as you may face some email delivery issues to the outside world using a .local tld. You should also set up reverse DNS for that IP address to match up with the mail server's hostname, this will aid in email delivery as well.

Thanks for the reply. I'm to the point where I can telnet into my server and test it on that level, but I'm assuming that my .local hostname is the reason no mail is actually getting to the mailbox. DNScolos.com mentioned something about greylisting. Is that the case?

If your MX record is set to something at domain.local, systems on the internet are not going to be able to email you.

If you are trying to test locally and it's not working, run tail -f /var/log/maillog on the mail server, and execute mail -v address@domain.com from a terminal. This will not only give verbose output on the client machine, but will show you server side what's going on.

Hope this helps.
