I'm using postfix 2.7.5. Some relocated messages are bounced, some are rejected.
It looks like this is the rule:Messages to recipients that appear to be local users (through winbind in my case) are bounced.
Messages to recipients that do not appear to be local are rejected. This may be relevant: The mail is sent to a domain listed as $mydomain in $mydestinationAlmost all mail for this domain is relaid to an Exchange server using an entry in the "transport" map.
Thanks, Pim
