We have major performance problems on our mail server with 12 000 accounts.
We wanted to go for a distributed Atomic or 4PSA solution but both are not compatible with Plesk Expand.
In order to isolate the problem we want to try and separate Horde from the mail server. In essence create a front-end server for Horde that connects to the back-end server.
Alternatively we need some advice on splitting IMAP/POP/Port 25/etc.
The only thing we're doing is using an SMTP forwarder which seems to alleviate some load, but still we have problems with performance.
We've given up for two years to use Spam Assassin, this completely kills the server.
Can anyone advise us? I'll pay for this service.
