In detail I have a couple of defined addresses that I all use for

There are two problems with it:
1. I must choose the correct address that belongs to the mailing list
2. I have several computers, where I would have to setup all the
addresses.

So in my case, it really would be nice to always send with i.e.

c...@roessner-network-solutioons.com

and Postfix would do:

RCPT TO == postfix-users@postfix.org
->  Sender domain is (.*)@roessner-network-solutions.com
->  Do some canonical tricks, make local part c+postfix_org_en

This is a job for a content filter or milter. Postfix rewriting is
based on simple (key, value) lookup tables, there is no support for for
context-enriched lookups.

Can I do this with some restriction_classes

No, restriction classes are for access control, they have no effect
on rewriting.

I would use this only on the submission port, which is defined in
master.cf.

Where you can specify a custom content filter or milter.



Some mail clients have similar features for mail list support. This isn't something postfix can do.
