The cyrus part is only valid for Cyrus-IMAP 2.1.x and Cyrus-SASL 2.1.x. If you plan to use Cyrus-IMAP 2.0.x then please consult the deprecated version 1.0.x of this HOWTO.
I strongly recommend that you upgrade to Cyrus Version 2.1.x. If you do so, you will have a better ability to get valuable support from the user community
First I would thank all those people who sent questions and suggestions that made the further development of this document possible. It shows me that sharing knowledge is the right way. I would encourage you to send me more suggestion, just write me an email <luc at delouw.ch>
There are different approaches on how to set up different mailsystems. Most documents that are available are related to Sendmail, procmail, WU-IMAPd and friends. These packages are very good but are unfortunately very inflexible in their user administration.
For a long time I was testing alternative MTA's like qmail, postfix and exim, in conjunction with IMAP/POP-servers like Cyrus, vpopmail, Courier IMAP and others.
At the end of the day, from my point of view the couple Postfix/Cyrus seems to be the most flexible and best performing solution.
All these combinations of software had one thing in common: their was very little documentation available describing how these packages work together with each other. To install the software, lot of effort has be spent to get all information needed to get all the software running.
