Hi, I'm planning on a new mail infrastructure which constists of multiple 'frontends' running webmail & public access pop/imap, which would communicate over imap/pop to 'backend mail stores'. My original idea was to run dovecot on the backends, use a predition on the frontends to proxy imap/pop and also run imapproxy in front of webmail [squirrelmail].
I've since read about the dovecot proxying features and it seems to make sense to replace predition in that above scenario. I'm unclear about the benefits of the auth_cache and how it compares to the using imapproxy in front of webmail client? Does it make sense to have authcaching switched on in the proxy and not on the backend server? (Doesn't the authentication just have to happen on the backend server?) Are there any performance benefits to using a proxying server, or is it just for splitting mailstores? thanks for your work, Dan Poltawski
