Spamassassin ONLY on exim (not on courier)

[visskiss]

Hi All,

I have a long standing issue with spamassassin. I would like it to check mail when it is delivered (like through exim) but not AGAIN when it is checked with IMAP (courier). Can I arrange this in whm?

I don't see the need for checking the email twice and resources are being used extensively by imapd.

Does anyone see this as necessary?

What are the best settings for spamassassin.

Thanks

DK
PS, I disabled spam assassin, but a lot of spam came through so it might still be useful (I use RBL and SBL blocking)
