[Dovecot] Just trying to make dovecot work.

Hi,

I have to say that Dovecot is certainly the most challenging piece of 
software I've ever had the pleasure of setting up (due mainly to the 
reams of largely unhelpful documentation). After 36 almost non-stop 
hours reading and trying, I finally end up here. :-)

I really would appreciate your help - and many thanks in advance!

Notes:
'peter' does not yet have a system password, since I'm testing this for 
users which will only be virtual users.
I made the password for 'peter' in the dovecot.passdb using "doveadm pw 
-s crypt" although once I've got it working I'd like to change the 
encryption to something as strong as possible - any suggestions please?

Hope you can help and many thanks.

Kind regards,

Peter
