Hi,

I have to use a Mail-Relay because of the fact that my Mailserver ist behind a dynamic-IP-address. I registered myself to this mailinglist by mail.
But every mail I'm writing to nginx@nginx.org is bounced with 554 5.7.1 because of the fact that relaying is changing the envelope-from header.
I think the mailinglist-settings are too restrictive.
Admin: Any chance to change that?

Example from today:
> Reporting-MTA: smtp; s1-b0c7.socketlabs.email-od.com
> Original-Recipient: rfc822; nginx@nginx.org
> Action: failed
> Status: 5.7.1
> Diagnostic-Code: smtp; 554 5.7.1 <nginx@nginx.org>: Recipient address rejected: envelope-sender address is not listed as subscribed for the mailing list. You are either not subscribed or From: address differ from envelope address
> Last-Attempt-Date: Sat, 27 Apr 2019 17:23:43 -0400

Send from forum@ruhnke.cloud relayed via socketlabs. The Relay changed the envelope-from to Return-Path <mail-id>@bounce.ruhnke.cloud to control bounces.
