sender_bcc, recipient_bcc, double messages: Need some help

Robert Krig-2
Hi guys. I need some help.

I've setup postfix to use sender_bcc_maps and recipient_bcc_maps so that
only one of the virtual domains which we host, is forwarded to a backup
account.

The sender_bcc and recipient_bcc statements are in the main.cf

The problem, as so many have posted before, is that the backup mailbox
receives every mail twice.

I realize this has to do with our external filters in our postfix queue,
 however Im totally lost as to where exactly to insert the options that
have been posted in this newsgroup as a solution.

I've have tried various options before, but either BCC gets disabled
completely, or postfix refuses to accept smtp connections.

I'm aware of the "recieve_override_options=no_address_mappings" setting.
But if I put in the main.cf then no mails get sent via BCC to the backup
mailbox.
I have experimented with placing the sender_bcc_maps and
recipient_bcc_maps at several different places within my master.cf. But
whenever I do that, postfix stops working properly and refuses smtp
connections. In other words, I can't send out email.

Some additional info about our postfix setup:
We use mysql as a user database in combination with postfixadmin.
Secondly we filter emails via postgrey, amavisd, spamassassin and maildrop.

The configuration wasn't entirely done by me, different admins added and
modified different things, so I've lost the overview a bit.

Can anyone help me?


Below is the output of my postconf -n and my master.cf


Thanks.

Please see FILTER_README and search for receive_override_options.

I did. But my problem is, that I'm not sure where to put that statement.

FILTER_README provides examples for several filter configurations.
It is up to you to recognize which configuration matches yours,
and to decide whether or not the address mappings need to happen
before or after the filter.
