Hi All,
I am currently design a email system for mine hosting and I would like to know how is yours. FOr me, I would setup 2 tier email system, using qmailscanner+spamassin at the first tier to filter the virus and spam, and then forward the email to email server. Please comment and suggest.

Hi neo@theone,

Why do it yourself? Just get a CPanel server - its all ready to use and make money reselling.

because with cPAnel you still get SPAM and viruses

Hi neo,

We run a system similar to this using filtering servers running the Postfix MTA, MailScanner, SpamAssasin and ClamAV. MX records are pointed to our 'mail gateway' server which scans messages and forwards them on to the end-users mail server. A couple important points to avoid Spammers getting around your system:

(1) Don't put the end mail server in DNS as a lower priority record. A lot of spammers are smart enough to send spam to all of the MX records, and legit messages should queue on the sender's server if the filtering server goes down.

(2) Don't use DNS names like mail.domain.com for the end mail server. I've seen a few spammers that will guess at this sort of convention and will bypass the MX record and thus your filtering server entirely.

This solution works quite well for domains that get a lot of spam and helps avoid having the end server get overloaded while processing spam while neglecting other important services.

In such a solution can also be load-balanced easily to make a very scalable solution.

I hope this helps!

I use sendmail now but will switch to postfix very soon ~

We have procmail for mail filtering, and then mailscanner for virus scanning and then an optional spam@ss filter if the client has enabled that in his control panel~
