Good day.
I am have spent spent some time trying to figure out if the following
Postfix config is possible and am hoping for some guidance.
Short Synopsis:
I would like to move some of my virtual domains to have their email
hosted via a "Google for Domains" account. While there are only a
handful of accounts, most of the accounts have many aliases and have
used '-' as a recipient delimiter for years. As such, the actual
number of addresses is probably in the thousands. Since Google uses
'+' as the recipient delimiter, there is no easy way to just switch
the domains over. I would like to use my Postfix server to filter /
rewrite incoming addresses and then relay them on to Google, with my
server being the MX server for the domain and using a smtp "transport"
entry to direct the messages to the right place.
Long Synopsis:
I currently have several virtual domains setup similar to:
example.com example.com
m...@example.com lastname1
f...@example.com lastname1
b...@example.com lastname1
b...@example.com lastname2
b...@example.com lastname3
where my aliases are like:
lastname1 /var/boxes/lastname1/
lastname2 lastna...@example.org
lastname3 /var/boxes/lastname3/, lastna...@example.org
Since my recipient_delimeter is set to '-', this allows emails
addressed to:
me-...@example.com
bill-baz-...@example.com
to get to the right account.
I am trying to get rid of all local delivery and have this machine
just act a gateway that does some basic address filtering and routes
the email to the new email server (Google for Domains). For example,
this server would know that 'm...@example.com', 'f...@example.com' 'b...@example.com
', and 'me-anyth...@example.com' should all be relayed to 'lastna...@example.com
' at Google.
While I realize this doesn't work, imagine that I updated aliases to:
lastname1 lastna...@example.com
and make a transport entry:
example.com smtp:[newserver.example.google.com]
and you hopefully can get an idea of what I am trying to do.
Is something like this possible with Postfix?
Thanks.
