OS: 2.6.32-696.23.1.el6.x86_64 (Centos 6)
Sendmail: 8.14.4
sendmail will receive mail for local users from outside users but queue it and not deliver it promptly but in spurts; sample receipt line:
Nov 1 15:56:17 server sendmail[18406]: wA1JqHk8018406: to=, delay=00:00:00, mailer=local, pri=83669, dsn=4.4.3, stat=queued
Then:
Nov 1 22:50:31 server sendmail[19747]: wA1JqHk8018406: to=, delay=06:54:14, xdelay=00:00:00, mailer=local, pri=713669, dsn=2.0.0, stat=Sent
At that time 27 other messeges were marked as 'stat=Sent'.
Any useful sendmail commands to debug this one? Things to check in the .mc or .cf files?
I should mention that I am getting the following message in the initial transaction:
Nov 1 15:56:18 server sendmail[18406]: STARTTLS: write error=syscall error (-1), errno=104, get_error=error:00000000:lib(0):func(0):reason(0), retry=99, ssl_err=5
There's not much I can find about this error, except to use ssldump. I don't know whether it is relevant to the main problem.
DeliveryMode
option andMlocal
(local mailer) lines from your/etc/mail/sendmail.cf
file?
