Sending mail to two streams...

Michael Segel
Hi,

I am curious about being able to send email to both Dovecot for the end user’s mail box and then also on to a stream where one can do some analytics?
Or chain the streams so that you can do analytics on both in-bound and out-bound  and then deliver it?

I know that it can be done (theoretically) but I’m not a guru on Postfix so I’m at a loss as to where to begin doing research.

Any pointers?

Thx

-Mike

You can add a recipient with any of the following:

    sender_bcc_maps
    recipient_bcc_maps
    virtual_alias_maps
    always_bcc

(perhaps using a pcre map for the maps-based mechanisms).

And using smtpd_proxy_filter with a null filter that acts as a 'Y'
splitter (Viktor has used that to implement an archival service).
