I do not have anything restricting port 25 going out. I can receive mails fine, but sending fails because of:
Code:
Nov  3 01:48:52 localhost postfix/smtp[22174]: connect to gmail.com[216.239.57.107]: Connection timed out (port 25)

Nov  3 01:48:52 localhost postfix/smtp[22174]: 3A3E82C883E: to=, relay=none, delay=90, status=deferred (connect to gmail.com[216.239.57.107]: Connection timed out)
Any ideas? Thanks.
