Q0428

`Navigation(siblings)`_

I've converted from Sendmail, and I notice that Exim doesn't make use of the owner- entries in my alias file to change the sender address in outgoing messages to a mailing list.

If you have an alias file with entries like this:

somelist:        a@b, c@d, ...
owner-somelist:  postmaster

Sendmail assumes that the second entry specifies a new sender address for the first. Exim does not make this assumption. However, you can make it take the same action, by adding

errors_to = [email protected]

to the configuration for your aliasing router. This is fail-safe, because Exim verifies a new sender address before using it. Thus, the change of sender address occurs only when the owner entry exists.
