Dear all,
Everything is ok when i use zimbra version 4. Recently, i have upgraded to zimbra 5 (5.0.5). Everything is also ok. However, i see many messages of our customers are verified as "Passed SPAMMY" or "Blocked SPAM". It would seem spam filter is having the problem.

I have tried to add the domains of customers into whitelist_from in salocal.cf.in and restart zimbra but spam filter still verify them as "Passed SPAMMY" or "Blocked SPAM".

Please help me!

Regards,
