I don't know what Michael had in mind, but I also seemed to recall that 
the 'Squat' plugin used to be the only FTS plugin which suppotred 
substring matches. http://wiki2.dovecot.org/Plugins/FTS/Squat explains:

"The main difference between Squat indexes and the others is that Squat 
provides support for substring searches, while pretty much all other FTS 
indexes support only matching from the beginning of words. By strictly 
reading the IMAP RFC it requires substring matching, so to optimize 
regular TEXT and BODY searches you must use Squat with Dovecot v2.0. 
[..] However, almost all other commonly used IMAP servers no longer care 
about this requirement, so Dovecot v2.1 also no longer makes this 
distinction."

I'm not sure how to read this, but I can imagine (and maybe that's what 
Michael was hinting at) that the Squat plugin for Dovecot >= 2.1 no 
longer supports substring matches as required by the IMAP RFC whereas 
previous versions do.

P.S.: I wish this list would have a Reply-To configured. :-)
