bcc message rule

Several clients bcc incoming and outgoing email to their gmail account. It works well, however Google won't accept messages bcc'd from notification@facebookmail.com.

I want to deliver these messages to the client without copying the messages to gmail. So I need some way to bcc gmail unless the message originates from facebookmail.

Anyone have a clever solution for this one?

I am using Postfix's sender_bcc_maps & recipient_bcc_maps directives to accomplish the bcc function.
Hmm - you could change to the rule-system instead of postfix:
* higher priority rule (e.g. prio: 97):
** From notification@facebookmail.com
** To <WhoObjectOfBCCUsers>
** Action: Accept
* lower priority rule (e.g. prio: 96)
** To <WhoObjectOfBCCUsers>
** Action: BCC gmail (there would probably need to be one rule per user)
** Action: Accept

As an alternative you could take a look at the 'sender_dependent_transport_maps' (and forward mail from facebook to a special smtpd-instance (configured in master.cf ) , which does not BCC) - haven't tested that - but seems promising

EDIT: added the sender_dependent_transport_maps option

I hope that helps!
