DMARC is a policy for a domain which controls who is allowed to send mail for that domain.<div class=""><br class=""></div><div class="">Therefor certain domains have a DMARC policy that will not allow a message from e.g. Cheater (using gmail) to be sent from the <a href="http://synth-diy.org" class="">synth-diy.org</a> domain. This would start bouncing and/or get our server blacklisted. In that case, From: will be rewritten to "cheater cheater via synth-diy <<a href="mailto:synth-diy@synth-diy.org" class="">synth-diy@synth-diy.org</a>>" and a Reply-To: with his real address will be added. (Which is perfectly legal in the DMARC system.) Because of the Reply-To: header, a simple Reply in your e-mail program will do the right thing and send the mail only to cheater. A Reply All will also pickup the list (and other) address from the From: and CC: headers. Roman’s domain does not use DMARC, so no rewriting is done.<div class=""><br class=""></div><div class="">DMARC is being used more and more, and that is why you see this rewriting also happening more often. Unfortunately this is the best workaround we have for now.</div><div class=""><br class=""></div><div class="">Use a DMARC checker if you want to see if your domain uses DMARC or not.
