Manually running PostMasterPOP3.pl:- root@rt3:/opt/otrs/bin# ./PostMasterPOP3.pl Notice: PostMasterPOP3.pl is already running (use '-f 1' if you want to start it forced)! root@rt3:/opt/otrs/bin# Even though it does not seem to be running:- root@rt3:/opt/otrs/bin# ps -ef |grep -i post root 4338 1 0 May09 ? 00:00:07 /usr/lib/postfix/master postfix 4358 4338 0 May09 ? 00:00:05 qmgr -l -t fifo -u postfix 4913 4338 0 May09 ? 00:00:00 tlsmgr -l -t unix -u -c postfix 27554 4338 0 15:14 ? 00:00:00 pickup -l -t fifo -u -c postfix 27916 4338 0 16:30 ? 00:00:00 cleanup -z -t unix -u -c postfix 27917 4338 0 16:30 ? 00:00:00 trivial-rewrite -n rewrite -t unix -u -c postfix 27918 4338 0 16:30 ? 00:00:00 local -t unix root 27929 4532 0 16:30 pts/0 00:00:00 grep -i post Please advise?
