hi vince, this is what I get when I do a netstat -an | grep 25
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
tcp 0 0 ::1:25 :::* LISTEN
very strange..... port 25 is fine......
when I do this nothing happens...
lsof -ni TCP:25

My best guess is the default install has postfix only listening on
localhost. Check the inet_interfaces option in main.cf. A `netstat -an
| grep :25` or `lsof -ni TCP:25` will tell you if postfix is actually
binding to more than localhost on tcp/25.

The problem with you masking your IP and domain name for security
reasons creates problems for those trying to help you. If your DNS is
wrong we cannot explicitly tell you what is wrong.
Here is a very good Postfix book:

and a good DNS book:

and a good Linux book:
