How to relay ?

I now have a Postfix server running, and, of course, I run into
main.cf...

I have a domain, zzz.com, and some people I want to relay mail to:
john@zzz.com
mary@zzz.com

They live out on the internet and have their own e-mail addresses,
like john@yahoo.com and mary@hotmail.com.

I can arrange (at my DNS hosting company) DNS to send all e-mail for
zzz.com to my Postfix server, which then has to "forward" (?) the mail
for john and mary to yahoo and hotmail.

So the PF server will handle all zzz.com mail.

How would I set up the main.cf to do that ?
(the mydomain variables etc)
what are the keywords here ? relay, aliases, forwarding ?

Which main.cf variables are to be set here ?

Would I have to build an aliases file like this for all my
"customers":

john: john@yahoo.com
mary: mary@hotmail.com

etc ?

friendly greetings,
Erik.

Some DNS providers (zoneedit.com, for example) allow you to perform
the forwarding on their servers. It might be useful for you to check
with your DNS provider to see if they provide that service.

For EVERY john Doe I decide to give an e-mail address under my domain
????

1: I want all e-mail for zzz.com to go to my Postfix server. My
provider has that facility for me.
2: I want to maintain a list of persons I want to receive and forward
e-mail for in this server
3: I want to have the server send the e-mail on to their respective
e-mail addresses at their own providers.

friendly greetings
Erik

You won't find out unless/until you ask them, will you?

If you prefer to maintain your own server, that's fine by me
(actually, I really don't care one way or the other). I just wanted
to offer a simple alternate solution in case it helps someone.

I did what you are looking for with Postfix and virtual domains. I
have some of the virtual mailboxes hosts on the box, and some are
forwarded as you want.

Check the docs for:

virtual_mailbox_domains
virtual_mailbox_maps

http://archive.mgm51.com/mirrors/pos...tml#forwarding

That should get you going in the right direction.

man 5 virtual

will tell you how to do virtual aliases. My Postfix setup is a bit
more complicated so the parms I mentioned below may or may not be
fully suitable for your needs. Follow the URL I suggested below and
the above man page for the best advice.
