Hi, Does anyone knows what is difference between PostMaster.pl and PostMasterMailbox.pl? I was used to run PostMaster.pl to check mail and inserting them in OTRS but recently it just hangs forever without showing any activity. While PostMaster.pl hangs every time but running my mail account POP3 is still possible in UI/AdminMailAccount. Now I am using PostMasterMailbox.pl instead and it runs well. But I'm wondering what is difference between them? Can I just use PostMasterMailbox.pl instead of PostMaster.pl for ever? I'm running OTRS in MS Windows platform. Kind Regards, Afshar Mohebbi
