Re: [cobalt-users] Any way for RAQ3 to avoid Spam?

[Dmitry Alexeyev <dmi_a@xxxxxxxxxx>]

Hello! 

Actually, a best solution is get rid of sendmail at all. 
I am using postfix+cyrus-imap+webadm+mysql+spamassassin.

So, I have: 
	o [virtual]users and domains in mysql database (and an option to check 
for spam)
	o _reverse_ sender checker - if there's no such user at the sending 		
machine, incoming mail goes to /dev/null
	o 3 dns blocking services. Quite enough.
	o live spam checking with BAYESian learning - nice thing. It marks SPAM 
mail in headers, so my users may just filter this messages
	o web administartion module
	o SMTP auth (only PLAIN right now, but planning also other)
	o SMTP with TLSv1

Something else, do not actually remember what... 
This system works for me for 4 months already, with no downtime. I have 
received some spam messages though, but all them are now in bayes 
database.

I'm going to make RaQ3/4 package next week. Any testers are welcome.

Best Regards,
Dmitry
