First of all, /etc/cron.d/otrs does not seem to be working. My test was to send an email to the account I setup otrs to retrieve email from. If I run PostMasterMailbox.pl manually, it will retrieve the email. But it is not being executed by cron. The only thing I did to the otrs cron file was to change the time between mail checks from 10 to 5 minutes. Right now it has a few test emails sitting on the queue but they are been cheerfully ignored. Any suggestions for why that is happening? Also, where does it store the info used to configure the mail accounts you setup using Preferences->PostMaster Mail Account (chapter 5.13 in the manual)? Would it be in the otrs database? How do you setup a queue to send back an email acknowledging it has received an email? I have associated an email to a queue but do not seem to figure out how to make it send that initial "Hey, we got your email request and now will think about it" message.
