I'm running a redhat 9 server with sendmail 8.12 or so. Everything has been working great for months except my clientmqueue directory is filled with 150 Mb of files spanning several months.
mailq says /var/spool/mqueue is empty (there are two files)
mailq -Ac says /var/spool/clientmqueue is empty (it is not!)
I tried a lot of the obvious stuff. http://www.experts-exchange.com/Operating_Systems/Solaris/Q_20509474.html
reminded me that I need to have two sendmails running, and I do. Just for kicks, I ran a second copy of both:
sendmail -L mta -bd -q15m
sendmail -L msp -q15m
but all I get from that are a lot of daemon MTA: cannot bind errors in the maillog.
The files are mostly owned by smmsp.smmsp and have -rw-rw---- permissions, although there are a couple of apache.smmsp files.
Why isn't sendmail able to find and process that stuff?
