sa-learn with remote Dovecot folders

[Andreas Kasenides]

Hi all!

The set-up I have is a classic one:
1. one or more Dovecot relay/directors Postfix SMTP servers in DMZ
2. one or more backend IMAP/SMTP servers on the inside network
3. There may or may not be separate incoming or outgoing designated SMTP 
servers.
Now the desired functionality is (of course):
1. relay machines receive messages from outside AND inside
2. relays check for all the bad things (spam, viruses etc).
3. for incoming messages relays check for valid local users and reject 
messages for invalid users
4. after all checks are done incoming messages are transferred to the 
backend systems where they are accessed via the Dovecot directors

While all the above works nicely, the problem I have is how to train my 
spamassassin (used by amavisd) on the front ends when all messages are 
on the back ends. Of course transferring the spam detection procedures 
internally is not such a great option.Am I missing something? I tried 
googling for info but nothing substantial turned up.

Thanks.
