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.
I use ssh. The exact details depend on your setup, of course. Do you use
system users of virtual users? What triggers the training? Is it the
antispam plugin?
