[KLUG Members] Mimedefang

[Adam Bultman]

I'm looking into mimedefang as another way of cutting down on spam.  I'm 
making a store and forward server, and already have one milter 
(milter-dnsrbl) built and working with postfix (well, at least there's no 
errors) and looking at mimedefang, it seems like a very good way to block 
crap during the SMTP session.  Mimedefang is a sendmail milter, however, 
postfix has the ability to use sendmail milters.

I've got a postfix server on ubuntu (edgy), and I've build mimedefang (the 
package requires sendmail, and uninstalls postfix) and I'm getting 
strange errors that according to google, *could* be a problem with 
postfix having been built against a 'different version of libmilter'.

1. Anybody else here use mimedefang, especially with postfix?
2. If mimedefang is impossible, is there another, similar milter that'll 
let me scan incoming mail and block it without having to do any further 
processing (I want to return 550 or 421, rather than accept it and have to 
deal with it. The implications of returning mail are easier to swallow 
than accepting it, scanning it, and then deciding whether or not the end 
user should get it.)
