If the UCR variable mail/archivefolder is set and mail/antivir/spam=yes (which is default) postfix send two mails to mail/archivefolder recipient.

It's easy to resolve the problem in the master.cf. Just add in the first smtpd line a "-o receive_override_options=no_address_mappings". The new template for master.cf could look like this:


--- 10_services 2013-11-20 11:54:47.000000000 +0100
+++ 10_services.new     2014-12-22 17:34:00.368239596 +0100

 if configRegistry.is_true("mail/postfix/smtpd/debug", False):
        smtp += " -v"
+if configRegistry.get('mail/archivefolder'):

 print smtp

The UCR variable mail/archivefolder has now also trigger to rebuild the master.cf.

I'm not sure if the proposed patch (source seems to be http://www.postfix.org/ADDRESS_REWRITING_README.html#auto_bcc) is the optimal way since a lot of other features will be disabled and may break things like canonical maps or result in non-optimal/faulty mail routing.

From the man page (man 5 postconf):

> no_address_mappings
>    Disable canonical address mapping, virtual alias map expansion, address 
>    masquerading, and automatic BCC (blind carbon-copy) recipients. This is 
>    typically specified BEFORE an external content filter.

This has to be checked before applying the patch.
