Train bayes with that message and use some other tests like SURBLs. For me it is sufficient:
Quoting Frank Tore Johansen <[EMAIL PROTECTED]>:
Somehow this message (attachment) didn't trigger _any_ of the rules we have, not even BAYES_00. Have the spammers found a way to make spamassassin abort its spamtests? Since BAYES_00 is missing, I suspect that a locking-timeout for the bayes database occured. So far this is a single case, but it still shouldn't happen. Any ideas on how to avoid this? [...]
