No e-mail getting to /var/spool/mqueue

[Matthew K Bowman]

Hello,

I've ran into a problem I had a few weeks ago whereby mail gets queue up in
/var/spool/mqueue.in but doesn't get passed to /var/spool/mqueue for
processing.  I've tried stopping Mailscanner, setting Virus Scanners = none,
restarting - this didn't help.  I'm not getting any timeouts or other errors
in maillog or messages.

redhat 7.3
sendmail 8-11.6-25.72
mailscanner 4.22-4

Output of ps -auxww | grep -i mail:

Any thoughts?
