SpamAssassin only scans messages less than 128KiB

Post by minsk » Fri Feb 15, 2013 10:58 am

SpamAssassin only scans messages less than 128KiB. This limitation effectively skips spam messages with attachments. And if the attachment is an archive then antivirus will not scan it either. This reduces protection greatly.
Is there a way to make SpamAssassin scan a message with attachment even if the total size is greater than the above? It may ignore the attachment part - will still score high enough.

The antivirus filter will run up to 25 megabytes. SpamAssassin was updated to 256kB within the last 6 months, however it isn't good about scanning large messages so we limit it for performance reasons. We may look in to the possibility of splitting up the MIME parts and running things on individual pieces.

I apologize for the much delayed response. Due to spam issues (spam posts and spammer registrations) we stopped monitoring/maintaining the forums for almost a year.
