[CLUG] MailScanner problem

[adam]

I'm having a small problem with MailScanner, some very obvious spam is
getting through and I'm not sure why. This is a CentOS system with
default packages and MailScanner almost out of the box.

The mail is definitely going though MailScanner, as it's being tagged
with an X-BN-MailScanner header, however I'm suspicious that it's not
going through SpamAssassin, as I'm getting no headers for that.

Is there some reason why some mail wouldn't be piped through
SpamAssassin? It doesn't seem to be size anyway.

Thanks,
adam
