The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database.

I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

Setting Up A Spam-Proof Home Email Server (The Somewhat Alternate Way) (Debian Squeeze)

Mon, 16 May 2011 18:32:56 +0200

Setting Up A Spam-Proof Home Email Server (The Somewhat Alternate Way) (Debian Squeeze)

Email spam is a huge problem. I have found for myself quite a simple solution, however it'll take some time to "migrate" completely over to it. The solution is to create a unique email address everytime I have to give an email address to someone else or to some website to sign up. If I want an account at twitter, I'd use "www.twitter.com@MYDOMAIN.COM". For webbased services, I use the full domain name incl. subdomain (www) on the left of the @ (some poorly designed websites do not recognizes the www. as valid email address, for those I just leave it away).

I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately).
