So I have a Postfix server that authenticates users against an LDAP directory.
This works great so far, but one of the mail adresses should be allowed to set another sender address.
All users on that server already are limited to send with their login adress, e.g.
email@example.com is only allowed to send with that exakt mail adress.
The only exeption should be one adress,
firstname.lastname@example.org, which should be allowed to send with any sender address(not limited to
Is this possible?
