Exim Sendmail and the -f flag

Is it possible to get exim to respond to the -f flag?

I have an application that is a follow up autoresponder.

I've just moved it across to my DA server. all is well except when i choose the

Use sendmail -f flag option to set the return-path to go to an account on the server (all bounces end up here and are later removed) It does not set it correctly.

It stays at the default username@serverhost address.

Any ideas?

I got it to work by adding the username of that account into the exim.conf under trusted users.

I'm not sure of the ramifications.. so if anyone could comment on that it would be nice.

Cheers

Simply, trusted users are allowed to set the -f flag. That's it. If you're willing to allow the user (and/or the user's programs) to set the -f flag, you make that user a trusted user.

No other ramifications except they can of course pretend to send email from anyone they want. Which is why you get to decide if you trust them or not.
