Messages stuck in sendmail queue beyond confTO_QUEUERETURN lifetime

CentOS 5.x | SendMail

Hi Guys,

Messages are stuck in my server's /var/spool/mqueue/ folder beyond the lifetime I have specified in confTO_QUEUERETURN (5d). Any idea why this could be? The file permissions appear fine; files in the mqueue folder show rights of:

-rw------- 1 root smmsp

This is causing an issue because the queues are slowly getting larger and larger.

Any thoughts?

Additional information... I'm seeing the queue size consistently growing. maillog shows entries like:

grew WorkList for /var/spool/mqueue to 28000

Any thoughts?

Just thinking outloud -- could the queue runner not be completing it's job in time? Maybe I could check with time sendmail -q -v

Any thoughts?

• Although I have very little experience with CentOS, I do seem to recall seeing some flavor of linux that didn't have sendmail configured with a queue runner by default. I would be curious to see if your old messages are removed after running 'sendmail -q'. If that's the case, then I think you just need to configure your queue runner to run periodically.
