  • Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.10)

    ubuntu Author: Falko TimmeTags: , , Comments: 27

    This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. 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). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

  • Postfix Virtual Hosting With LDAP Backend With Dovecot As IMAP/POP3 Server On Ubuntu Hardy Heron 8.04 TLS

    android Author: MiguelTags: , Comments: 19

    Postfix Virtual Hosting With LDAP Backend With Dovecot As IMAP/POP3 Server On Ubuntu Hardy Heron 8.04 TLS I've been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature (amongst others) I decided to switch to LDAP as backend for Postfix with virtual hosting. In view of the fact that the installation and configuration guide of Phamm is lacking some basic information it took me quite some time (including crying, swearing, getting depressed, ...) to put it all together and get it working. Long live google to find hints or explanations for problems and configuration issues. Piecing it all together wasn't simple so I would like to share how I configured it and got it all working toghether (as I like), but I think that it will benefit other users as well.

    How To Whitelist Hosts/IP Addresses In Postfix If you are administrating a mail server and use blacklists to block spam, you probably know this problem: from time to time your customers complain that they cannot receive emails from certain freemailers.
