Hello,

This has been my first Zimbra install. I am loving it and cannot wait to get rid of my Exchange box. All went quite smooth following the instructions posted here:

http://www.zimbra.com/forums/install...u-10-04-a.html

I am on an Ubuntu Server 10.04 and Zimbra 7.1.3.

All works (web client, admin client, locally and remote) except configuring Outlook with pop/smtp or imap. Ive noticed the problem is that port 25 is not accessible from a remote machine, pop, imap, http are working fine.

If I telnet to port 25 locally it connects and it returns

220 mail.domain.com ESMTP Postfix

If I telnet to port 25 remotely, connection fails.

Firewall on the Ubuntu box has been disabled.

Thanks in advance for your comments and suggestions.
