Hi,

I have an postfix smtp gateway in input with postfix behind my
firewall.

Currently, it delivers mails to my production mail server.
in transport file I have:
arte-tv.com smtp:[172.25.4.68]

I want that this postfix sends, in a same time, by duplicate the smtp
flow, mails to another mail server in test on my subnet, can I
combinate this option below to do this?

Or how can I do this?

Thanks in advance
