Setting Up A Mail Server Using Exim4, Clamav, Dovecot, SpamAssassin And Many Mor

Sep 23, 2010, 21:03 (0 Talkback[s])

[ Thanks to Falko Timme for this link. ]

"This howto describes one way to build a scalable, secure, full-featured mail platform. It offers virtual hosting of mailboxes in maildir format with support for quotas and server-side filtering, domain aliasing, address aliasing, address forwarding, catchall addresses. Relaying is secured with STARTTLS and SMTP-AUTH. Incoming mails are checked for viruses, spam, and checked against SPF policy and DNSBL.

"In order to achieve scalabality the setup will be split accross 3 servers:

* 1 MX server, where most of the security features sit (faramir.middle.earth)
* 1 SMTP relay, to allow users to send mails to the outside world (ectelion.middle.earth)
* 1 Mailstore server, where the mailbox sits (denetor.middle.earth)

"Of course more MX can be added using DNS MX records to your domains, more relay servers can be added using DNS round-robin, and more mail stores can be added using mechanisms described in this howto. At the opposite you can merge easily the MX and relay part, or the relay and the mailstore part. Merging MX and mailstore involves some modifications."
