This log snippet is postfix trying to send mail. Did you mean
to explain that this is your own host trying to send to
itself? Some routers don't allow loopback connections, so you
can't always connect to your own external IP.
Anything logged by postfix/smtpd ?
So if you
telnet localhost 25
does anything interesting happen?
Can you telnet to port 25 from some external host?
Even if I'm inside the box itself& send emails to myself, it was not
received too (despite that sending to external emails including gmail
was Ok) :
# mailx -s "tst to localhost" myunixid@localhost< /etc/hosts
# mailx -s "tst to myportaltech" myuni...@myportaltech.com< /etc/hosts
# mailx -s "tst to hostname" myunixid@`hostname`< /etc/hosts
# mailx -s "tst to local private IP" myunixid@private_IP_addr< /etc/hosts
What shows up in the maillog when you do this?
# su - myunixid
$ mailq
/var/spool/mqueue is empty
Total requests: 0
That looks like sendmail, not postfix. Maybe your system is
confused about which mailer it should be using.
Any "sendmail" log entries? There shouldn't be.
