Hey Timo,
I have a question regarding how dovecot might behave if a mail client (like, for example, Thunderbird) decided to store some of its config files on the IMAP server itself.
Would there be a decent way of doing this with dovecot that wouldn't cause problems for other clients that didn't know about these files?
Maybe there's a way to define a special folder that dovecot knows about at the top level of each users mail location that can be used for this kind of thing?
All I'm thinking of are certain config related files, so they would be small, and would only be downloaded when they didn't already exist - ie, when someone adds their existing account to a new PC, the first time they logged in, TB could simply download all of the config files, restart itself, and voila, your pre-configured TB is ready to go...
