[PP-1] Ensure origin headers of mails sent using the mailer.transport service comply to RFC5322

Created on 28 October 2023, 11 months ago

Problem/Motivation

Mails sent using the new mailer.transport service may not comply with RFC 5322 section 3.6.2. The Sender header is especially tricky, since whether or not this should be present depends on the content of the From header.

Additionally the Sender header must not be confused with the envelope sender. The former is port of the message while the latter is used in the SMTP protocol in the MAIL FROM command (see the Protocol Overview) in the Wikipedia SMTP for a good introduction).
