[otrs] PostMasterMailbox.pl not retreiving mail

Hi, A more specific question now... I can't get PostMasterMailbox.pl to retrieve mail from the cron job. If I run the script manually, it works fine. If I click on "Run Now" in the PostMaster Mail Account page, it also works. But, when run from the cronjob, nothing is retrieved. I can see the cronjob is running: Jul 14 00:53:01 rax crond[29489]: (otrs) CMD ($HOME/bin/PostMasterMailbox.pl >> /dev/null) Jul 14 00:54:01 rax crond[29500]: (otrs) CMD ($HOME/bin/PostMasterMailbox.pl >> /dev/null) But, it doesn't seem to do anything. Any ideas? R.
