how ?
Mailing lists like this one, for instance. When you post to the
postfix-users list, your message is redistributed from the list's
servers having your address as the originating address. The message will
originate from outside of your systems but will have your From: address.
If you block this, you won't see your own postings to the list.
This is an excerpt from the headers in your e-mail:
From: Benny Pedersen<m...@junc.org>
To:<postfix-users@postfix.org>
Subject: Re: Ok. I'm finding a small issue on my server.
