How to read HUGE clientmqueue in human format?
Solution 1:
For typical queue try sendmail -Ac -bp or mailq -Ac
For HUGE queue try sendmail -O QueueSortOrder=none -Ac -bp
-
-Acselects client queue -
-Amselects main/MTA queue
You may add -v to get even more verbose output.
In case of HUGE queue add -O QueueSortOrder=none to avoid sorting queue entries.
If none does not work then try filename.
AFAIK none was added in sendmail-8.13.8 and filename in sendmail-8.10.
