[SOLVED] Port 25 problem

[AutootuA]

Is their anyway that Zimbra would not accept a smtp connection from a certain ip address? mail.berrienhospital.com is my server.


I trying to test using telnet on port 25 and it keeps refusing it from Site #3. I can telnet on port 25 to any other smtp servers from Site #3, just not my Zimbra server.

Site #1 set up under the MTA Trusted Networks and it connects fine.
Site #2 is NOT set up under the MTA Trusted Networks and it also works fine.
Site #3 also is NOT under the MTA Trusted Networks and it will not work.

I'm not restricting access to that port with my router. It's open for all the world to see. What gives?

What if you do a traceroute from that server ? Sounds more like a connectivity issue to me. Postfix will not just drop the connection.

It's a firewall issue. I'm having a weird problem with the firewall/router allowing some connections in and blocking others.

Thanks.

I guess this post can be totally removed...
