AIX sendmail queue full

To flush queue
#sendmail -q -v
-or-
1. Stop the sendmail daemon.
2. Move the entire queue directory by entering:
#cd /var/spool
#mv mqueue omqueue
3. Restart the sendmail daemon.
4. Process the old mail queue by entering:
#sendmail -oQ/var/spool/omqueue -q
The -oQ flag specifies an alternate queue directory. The -q flag specifies to
run every job in the queue. To get a report about the progress of the
operation, use the -v flag. This operation can take a long time.
5. Remove the log files and the temporary directory when the queue is empty by
entering:
#rm /var/spool/omqueue/*
#rmdir /var/spool/omqueue
