Cyrus discards? Messages older than 3 wonth

[Martin Müller]

Hi!

Is it possible, that cyrus (debian sarge,  cyrus21-common 2.1.18-2.0.1) 
discards automaticly messages that are older than three month?
I cant find messages in my "Sent"-Folders which are older. In other 
folders there are messages older than three month.

We are using Thunderbird 1.5 (MacOS 10.4 & Ubuntu) and Apple Mail 
(2.0.7) as MUA.


Any hints?


Best regards,


Martin
