Hello,
We are testing a new mail system and I want to duplicate mail flow to the
new system at the same time allow flow to the exist system.
/ - CurrentMailhost.example.com (running Postfix)
@example.com -
\ - NewMailhost.example.com (running Postfix)
In fact its deliver locally and relay.
@example.com -- CurrentMailhost.example.com (running Postfix)
\ - NewMailhost.example.com (running
Postfix)
Yes I want "duplicate" mail to flow to each system. I tried using the
transport mapping for the domain, but it seems that duplicate entries are
not allowed (though only a warning is logged) and only the first entry is
used and mail will not be delivered to both.
/etc/postfix/transport
# delivery locally
exmaple.com :
# and forward a copy to a remove smtp gateway
example.com smtp:newmailhost.example.com
Does anyone have any other suggestions?
Thanks
Phil
