I'd like to clarify some open point regarding OTRS postfix and procmail. If I configure in Outlook a rule that each single mail that goes into the firstname.lastname@example.org mailbox will be forwarded to otrs@otrsserver (Exchange send connector already in place) which line in the sample .procmailrc from the admin manual tell's that everything that goes to otrs@otrsserver will be "moved" to OTRS ?
# Pipe all email into the PostMaster process.

Why do I need procmail anyway ?
