our schema is zimbra as primary, some other postfix mta like secondary. Zimbra catch all mails and which are not for local delivery, sends to secondary MTA.
Split Domain - Zimbra :: Wiki
Zimbra applied antispam checks for all messages - messages for local delivery and also for delivery to secondary MTA.
I cannot find how to disable antispam check of messages for non-local delivery - messages for secondary MTA.
I have tested one possibility with cos.
Every user has setted up manually COS with zimbraFeatureAntispamEnabled: TRUE
Domain has setted up different COS with zimbraFeatureAntispamEnabled: FALSE
And all messages are still checked by amavis...
Any idea how to make zimbra "transparent" (it means no antispam checks) for messages for delivery to secondary MTA?
