I'm slightly confused by the question. If you have an exim+dovecot
server and a mac mail client, and you're not able to receive mail...

how do you know that there is mail on the server to be received?
Did exim handle this mail (and log it)?

Do the timestamps in the dovecot log correspond to some exim log entry?
If not, we should assume that this is the mac mail client talking
direct to dovecot; there is a mismatch between the two for the
account name / password combination.

On the other side of the coin, the exim log line also shows a config
problem. Was that in relation to _sending_ mail, which you say works?
What else did exim log around that time?
