I've been considering another way of doing this, which may or may not be entirely sane: 1. Permit accounts to send on behalf of its associated domainname. 2. Allow users to register additional permitted sending addresses through an administrative web interface. 3. Deny any messages not matching either rule. Examples: 1. Account fnorblegnarb42 is associated with the domainname fnorblegnarb.example, and may send e.g. on behalf of [email protected], [email protected], [email protected], or fnorblegnarb.example. As may fnorblegnarb17 and fnorblegnarb23. 2. Account fnorblegnarb42 additionally registers as a valid sender of [email protected]. 3. Account fnorblegnarb42 attempts to send from [email protected], but is rejected. I suspect this can only reasonably be implemented with a database (SQL or noSQL, whatever). -- Jan -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
