[Dovecot] Dovecot authentication for PostFix, anyone?

[Marco Fioretti]

Greetings,

the postfix sasl readme, http://www.postfix.org/SASL_README.htm 
says:

>Dovecot provides an [authentication alternative to Cyrus] that may be worth considering.

In principle, I like the idea of doing without Cyrus, since I have
to run an IMAP server anyway and had already chosen Dovecot.

The question is if that page is up to date and if you could share
comments or, if they exist, safer/more efficient ways to use
Dovecot as authentication server for PostFix, as well as any
other relevant tips and tricks

TIA,
          Marco
