Sorry if I've missed something on this, but are these spam messages from external sources?
If so, wouldn't it be more suitable to look at stopping them at your perimeter? I can readily recommend mailcleaner (www.mailcleaner.org) a free, open-source, Linux-based anti spam/antivirus mail gateway. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of James Morgan Sent: 03 December 2009 22:37 To: User questions and discussions about OTRS. Subject: Re: [otrs] filtering spam Out of interest, at what stage of the process do they become question marks? Does the MTA see them as question marks, or characters in a different character set? If so, wouldn't this make filtering for question marks before they hit PostMaster difficult? Maybe a workaround would be to filter out all messages that aren't in the supported character set? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Alexander Halle Sent: Thursday, 3 December 2009 4:56 PM To: User questions and discussions about OTRS.

To call it use the corresponding option in the GenericAgent or let it process your emails and set an email flag to filter the mails with the PostMaster Filter. In the shell script you could use grep to search for multiple series of question marks which should differentiate your spam mails from user mails with normal usage of question marks.
