My situation is a bit complicated.  I am a comcast user trying to setup a home email server.  Obviously they block port 25.  I have setup a forwarding service that receives emails for my domain on 25 and forwards them to my server on 2525.  I have modified master.cf to have the line :

2525      inet  n       -       -       -       -       smtpd


Nmap shows :

22/tcp   open  ssh
80/tcp   open  http
110/tcp  open  pop3
143/tcp  open  imap
389/tcp  open  ldap
443/tcp  open  https
587/tcp  open  submission
993/tcp  open  imaps
995/tcp  open  pop3s
2525/tcp open  ms-v-worlds

mail.log does not even show the submitted emails.  Send/receive on internal emails works fine.  Sending to an external recipient works fine.

MX checks on my domain are good. 

Any help?

*) How did you setup this forwarding service?
*) Does /var/log/mail.log contain any log related to forwarded email?

Note: setting up mail service with a dynamic IP address is not recommended, it may become a nightmare to deal with IP address block, many ISPs and DNSBL services block dynamic IP addresses.
