what happens?
PostMasterMailbox.pl gets email.
PostMaster Runs and tries to create a ticket
It can't find a customer to create the ticket for the email, most likely because there is No "From". Perhaps another type of request to look up a valid user fails and therefore you get this error (warning, pretty much).

What could cause it?
Who knows? Bad character encoding (chinese characters?), malformed email, individuals sending weird characters in their names... if it's rare, it could be considered an artifact of spam. If it's consistent, you may want to have your collection email address forward a copy to another (gmail?) account simply to get an idea of the raw emails that arrive and back-trace a timestamp.

Should you be worried?
Only if you discover this is preventing a valid email from being created as a ticket. If so, then you need to determine what the difference is and ask the question in the forum.

What should you do?
Nothing. Or cc your email to another box and troubleshoot. Or install a spam filter.
