[Mimedefang] bounce check with sendmail and md_check_against

[Wayne]

That's how I have it set. Like I say I get 99% of them blocked it's just 
what I assume is a carefully crafted spam that is getting bounced. They all 
seem to be the 2 or 3 same type of spam messages of the day. You don't see 
this at all on your server ?
