dovecot - Feb 2006 - index file vs. memory

Hello,

we have a large base of mailbox users and while pop3-connections are 
usually closed after the download of all mails, I noticed hundrets of 
imap-connections kept idle by the users. This is surely according to the 
idea behind imap, but I'm a bit afraid of overwhelming memory 
consumption if there are too many imap-connections opened at the same 
time. Is the index file kept in memory as long as an imap-connection 
exists, or is it closed as soon as a certain read or write command has 
finished?

Regards
Marten

That imap process' memory usage will grow and shrink over time, but I 
observed (on my small single-user box) imap processes consuming several 
dozend MB virtual memory sitting around for extended periods of time...

No idea if dovecot can somehow be taught to free it up again as soon as 
possible or if it does not seem to be needed at the moment any more...

Greetings,
