Hi list. I was looking at Dovecot's imapc feature for some time. I am aiming to use Dovecot with imapc as a kind of "store-and-forward" proxy. If I understand imapc correctly, there are two connections at work — one between the client and Dovecot and one between Dovecot and backend. When the client asks Dovecot for mail, Dovecot will retrieve mail from the backend and then send it to the client. So the question is, is it possible to configure Dovecot with imapc in such a way that it would store the mail it passes to the client? Should I use mail filter plugin to do this? I am also quite confused about authentication in this setting. Let's assume we use 'plain' authentication mechanism, then what happens? I guess that the client just sends Dovecot its credentials, and Dovecot tries to authenticate with them at the backed, responding to the client accordingly. Is this true?
Thanks.
