out of office and non-delivery message don t pass trough mailscanner/spamassassin

[eric.le.corre at voila.fr]

Hello,

i have still problems with Out of office and non delivery message send from my exchange 2010.
I have mailscanner/spamassasin (version 3.3.2)/postfix as Gateway for my exchange.

All my out of office message and non-delivery send from exchange are catched as spam !

I put in local.cf (spamassassin) :
trusted_networks IP_my_exchange
whitelist_bounce_relays Host_name_my_exchange

but not better, it doesn t pass trough

i don t know how to do.

here, one example of Out of office block :

-0.0 NO_RELAYS Informational: message was not relayed via SMTP
