Ok, I checked the references... so let me correct my question: "reject_unlisted_recipient" was indeed "reject_unlisted_sender".
So, If I use that rule, and someone is trying to send a mail to a local account from for example hotmail, gmail, or any other external server, means that it will be rejected??? because the FROM address is not listed in the local recipients. Is that true? Right? Thank you. On Tue, Mar 17, 2009 at 11:04 AM, Alberto Lepe <d...@alepe.com> wrote: > Ok, that makes sense...
