Could someone tell us more about this?
And what is a good solution for forwarding? Rewrite the sender? SRS?

Preferrably use virtual_alias_maps, but if you need any of alias_maps
features, use that one.
Thanks for your explanation!

Do you know a way how to use aliases with an @ in it?

And what about milters, how can I configure them so that they are only

E.g. I don't want SPF checking on the submission-ports.
Or do I think wrong?

it. Maybe they start again.

This is the only thing what I have:
submission inet n - - - - smtpd
Is this wrong?
I would like it to set rules for every port separate, but I didn't do it
till now.

to let Postfix think the mail
comes from localhost.
