[Mimedefang] How to trap this spam

[Bill Maidment]

Well I have used a range of extra SA filters and that has improved the 
situation greatly. However, the spammers have tidied up the Subject 
header and the spam is slipping through again (sigh!).

I tried greylisting for a while with terrific results, until I came 
across 3 problems that upset the whole thing.
1. email coming  in through secondary MX nearly always got through as it 
all had the same relay address.
2. mail from ozemail was being resent every 5 seconds, so it never got 
through with the 30 second minimum
3. mail from yahoo was resent from a different relay, so it never got 
through.

Oh well, the battle goes on!
