Yes, funny how these got stripped from email.. anyway, platform is 
Debian Linux (kernel 2.4.x, planning also to upg. to 2.6) I'm atm 
testing that nightly stable from 2005/02/22

Yeah, would be nice to hear that too, I've tried this and result was 
that it it listens Unencrypted (non-SSL) IMAP on both ports.
I've also tried to make protocol imaps {} but it complains about invalid 
protocol.

Yeah, these instructions I've followed so far, but problems are with 
making Dovecot to listen on different ports (and SSL on those alternate 
ports).

Yes, funny.. I thought I also putted these details in but I guess I 
missed them afterall.

Yeah, well I am running corporate mailserver so I don't do anything 
without testing and comparing it first. Dovecot has been tested on 
another similiar server for (alot faster then uw-imap)speed, now all 
thats pending is getting it tested on production use (in different TCP 
port) - testing machine doesn't have all those troublesome mailboxes in 
it..  and finally just removing old software and switching dovecot's 
ports so that it runs on production use.
