[Dovecot] spamassassin, postfix with dovecot lda?

[George Mamalakis]

Hi Egbert,

thank you for your reply. I searched www.postfixvirtual.net, as you 
suggested, with no luck. Their configuration differs significantly from 
mine, since they are using CYRUS libraries in general, and not dovecot. 
Moreover, the configuration that is proposed uses a vmail user (or some 
general-mail-user) which is not something I would like to adhere into my 
configuration. I would like each user to have their own preferences, 
quotas, permissions, etc as far as their email is concerned. Lastly, the 
idea of using maildrop for local delivery instead of dovecot-lda passed 
through my mind, but when i tried to combine it with my configuration  
it didn't work; it probably needed cyrus libraries and not dovecot 
libraries. I think that if i manage to set it up correctly (if feasible, 
of course), then I would have found my solution.

Thanks again,
