dovecot - Oct 2007 - Disconnects in log

Hi all,

I need some help interpreting the info I'm seeing in the dovecot logs.
I have a user using Outlook who is having connectively problems.  Below
is a sample of what the Dovecot log is showing.  Can anyone explain to
me why multiple logins occur within a few seconds of each other?  Also,
as I understand it, the "Disconnected" messages mean the kernel told 
Dovecot the connection was closed.  I'm trying to figure out why I'm 
seeing so many of these.  And why they seem to occur shortly after
a login.

Thanks for any insight!

Jackie

Last I checked Outlook connected multiple times and disconnected once in
a while by itself.

v1.0.5 will include the syscall error after the "Disconnected", but
I'm
guessing this has something to do with the user's computer/network which
causes the connection to get disconnected.
