Hallo Mark, Kolleagues, maybe somebody will be able to help me here.
I would like to relay (also check with Antivir and sign them with DKIM) all Mailman e-mails from our external partners to our final customers. Relaying seems to work nice but we have a problem with DKIM authentication and Return-Path. Mailman server needs to stay by external partners with old domains and needs to receive bounces. My SMTP gateway is only responsible for receiving and sending e-mails out from the all mailman instances. The problem is that we are sending an E-mail which looks as follow: From: [email protected] Return-Path: [email protected] To: @gmail.com The problem is that DKIM check on the gmail server server (and all others) returning error: [[email protected]](mailto:[email protected]) does not designate xx.xx.xx.xx as permitted sender How to solve that issue ? At the moment we have a DKIM key only for myserver.com. Why DKIM check checking Return-Path and not From address ? Could You please help here how to manage that issue ? We simply would like to forward all messages from the external mailman instances installed on the different domains to the final customers using our sender domain [myserver.com.](mailto:[email protected]) I will appreciate any feedback from Your side.
