Yeah, Free ISPs who have spammers sign up. I've been fighting with this for quite a while. I've ended up having multiple qmail installs to do this. One to receive the email, one to spam scan it and relay it out. This seems to work well, I check the queues and clear out those emails and users - block those sending IP's if necessaary. My big problem is - how do I convert a single email with 50 TO: addresses into ONE email to be spam scanned? I think I need to run a different email server for the intital queue - but this then brings up questions like, how do I use SMTP AUTH with, say, Exim, and vpopmail? The whole spam/antivirus requirements have turned a nice 'email server' into a multiple install/multiple queue hell - and I only have about 2k regular users. Rick
