[Dovecot] Switching Servers now can't retrieve mail

[lists at kesh.com]

I have just switched my mail server. I have copied (I think) the config files from the old to new. Exim is work fine on the new machine as I can see email file showing up in /var/mail/lists/new . However, dovecot reports nothing when I check mail . I am have turn on logging on both machines and I do not see anything that looks like an error. I have also looked to see if the dovecot.conf file is compatible between 1.0.14 and 1.1.2 and have found little.

I am guessing this is a simple problem, can someone tell me what I have done wrong here.

I have provided Working dovecot -n from both machines and the log output from a mail fetch. 

Thanks,
