A few ideas I'd like to see implemented in the toaster, not sure how many are doable with qmail though.
1: Subject line rejection, meaning that we reject at SMTP level when we see the subject contains viagra or whatever, preferably regex based.
One of the toasters I admin is an incoming relay for my dialup ISP I use, this is a domain that has been in existence as an ISP since 1995 and believe me it gets a ton of spam coming in. The mail is then forwarded on to his NT based mail server for his clients to pickup, that MTA does do the subject scan and will reject certain messages using it, so it would be a nice feature to have on our toasters too. I think I did see a patch for this type of thing on qmail.org but haven't had time to test it out.
2: SpamAssassin at the SMTP level, an ISP local to me seems to have figured this out (not sure on MTA) but basically their server now rejects anything with a 6.0+ score in SA at the SMTP level! Slick indeed.
3: Virus refusal at SMTP level, probably doable using the subject line rejection but could also be done by looking at attachments I think. I know a patch exists for this one too.
