Hammering the server every minute can be hard on the server. Especially if all 
the users do the same. I personally make users check no more than every 10 
minutes automatically.

I use Xp and also leave it on all the time. Sometimes Thunderbird will seem to 
run out of memor, and a restart is the only thing that will help. But in my 
case it isn't dovecot because I can still read my mail from other clients and 
other machines.

Trimming the accesses down from every minute should help this also.
