As far as I know SpamAssassin looks for the mime type of the message, if it's text/xyz it will perform a scan. Be careful in pushing the message size limit! As said before, it doesn't make sense to set it to such a large value, as spammers WILL NOT send spam messages of that size (it's just to expensive in terms of hardware/traffic). To hijack the thread: Does anyone know an optimum for message size limit? Ours is set to 2MB at the moment, but we have problems when receiving large text mails (e.g. more than 1MB) as the message check will become REALLY time consuming. This leads to a curious situation where our Exchange (or maybe it's the external mail server, not sure of that) sends the message again after ~55 seconds, so the next child begins checking the mail... And there we've got a loop (until the server runs out of memory)... I set the --timeout-child of spamd to 45 secs now, what's working as a workaround for now, but there may exist a more solid solution, is that correct?
