Good day.
our problem started last week. postfix suddently could not send
Internet email but can recieve them.
when we checked maillog, we get the following:
May 16 19:11:24 svr1 postfix/smtp[1876]: connect to
mailin-01.mx.aol.com[205.188.155.89]: Connection timed out (port 25)
May 16 19:11:24 svr1 postfix/smtp[1876]: 78B50A0366:
to=<>, relay=none, delay=271429, status=deferred
(connect to mailin-01.mx.aol.com[205.188.155.89]: Connection timed
out)
we have checked the firewall and iptables -- port 25 is allowed.
checked main.cf -- it was not modified. checked rbls.org -- our ip is
not blacklisted. i was able to test telnet to a mail server at port
25 -- i was able to send email thru telnet. postfix is listening at
port 25.
any clue is appreciated as we don't know what else to look at.
thanks.
