Dovecot IMAP-Server (English)

Prerequisites:

This course requires participants to have good basic knowledge about the general setup and operation of Postfix servers. If you are interested in Dovecot and relatively new to the subject of Postfix, we encourage you to attend the Heinlein Academy training course Sichere Mailserver mit Postfix before signing up for this one. Note that Sichere Mailserver mit Postfix is currently offered in German language only.

Content:

On its first release in 2002, Dovecot by Timo Sirrainen was an outright shooting star in the IMAP server arena. Its impressive range of features, convincing performance, and simple administration has made it a top choice for many mail server administrators. As a result, Dovecot has quickly snapped up a lot of territory previously held by other IMAP servers such as Courier or Cyrus. Since version 2.0, Dovecot has become a complex and mighty tool while maintaining its widely appreciated approach to simple administration. This training course is targeted at businesses and corporations, universities, and ISPs, as we will demonstrate the planning and setup of Dovecot IMAP clusters that are capable of handling well over 100.000 users. We will also talk about filtering with Sieve, LMTP connectivity, Web-Mail, Quotas and the setup of shared folders.
