Hi all,

I have an old physical freebsd 6.2 server running Dovecot 1.0.7. I 
wanted to virtualised it.

So, I did a dd from the physical server and then I restored it on then 
now Virtual Machine.

I booted the server, all services are running just fine excepted Dovecot.

I tried to investigate the log as much as I can but i'm not getting any 
usefull pieces of information. The only entries I have in the log files 
are the following:

/*log: /var/log/messages:*/

I'm also running a squirrelmail as a webmail and here when I refresh a 
folder content 3/5 times I'm getting an error:

/Error: Connection dropped by IMAP server
Query: SELECT "INBOX.Corbeille"/

I'm using Dovecot version 1.0.7 on a freebsd 6.2
