Default Cannot Get Postfix to Send from Remote: Perfect Server 10.04 Postfix/Courier/Squirrel

Hi;

I have been working on this for days. I built a server using the guide in Perfect Server Ubuntu 10.04, specifically using Postfix/Courier/SquirrelMail.

The SquirrelMail part of it sends and receives perfectly. I can receive using a MUA such as Outlook or Thunderbird, using both IMAP and POP3. However, I cannot get it to send at all. It simply times out.

Then entry in /var/log/mail.log that seems to match the connection attempt is:

Sep 4 15:15:02 teva postfix/smtpd[10030]: connect from localhost.localdomain[127.0.0.1]
Sep 4 15:15:02 teva postfix/smtpd[10030]: lost connection after CONNECT from localhost.localdomain[127.0.0.1]
Sep 4 15:15:02 teva postfix/smtpd[10030]: disconnect from localhost.localdomain[127.0.0.1]

I can connect from a remote host via "telnet domainName.com 25" and even send an email like that. Thinking about it, that's no different than the way SquirrelMail does it other than showing that port 25 is open.

Thinking that it was a problem with "smtpd_recipient_restrictions", I commented out the ISPConfig3 line and deleted the "check_recipient_access" that ISPConfig3 uses to whitelist, but it made no difference at all.

It seems like it may be an authorization problem, but I'm at a loss. Here is my main.cf:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

biff = no

Thanks in advance for your help ... I'm going crazy here!
