I used this guide a week ago. http://www.howtoforge.com/perfect-server-debian-wheezy-apache2-bind-dovecot-ispconfig-3 To setup a server. I'm begining to populate it just now and I'm noticing that mail is not arriving. All the DNS setting are pointed correctly. NSLOOKUP confirms that the domains are now redirected. The MX records are set properly. Yet mail does not get rejected. It just goes into a black hole of sorts. It just never arrives. Is there anything I might check?
I had added smtp_bind_address = x.x.x.x to /etc/postfix/main.cf to force postfix to use the IP with the proper RDNS. So I guess I will have to change the RDNS on all the server's IPs just in case postfix decides to use them.
Are you able to send and receive emails with webmail? An easy test if the local mailsystem works is to login to webmail with a account hosted on the server and send a email to the same address that you used to login to webmail. Post the error message(s) that you get in the mail log file when the problem occurs. The mail log file is in the folder /var/log/, it is named "mail.log" on Debian
