Symfony version(s) affected

6.4.21

Description

The remote SMTP server will be told the message comes from the return-path address, not the from address (unless return-path is not set).

How to reproduce

framework:
  mailer:
    headers:
      from: Foo <foo@bar.com>
      return-path: bounces@bar.com

Possible Solution

Use from header instead.

  • Prod: native://default, which uses BusyBox v1.37.0 sendmail.
  • Dev: smtp://localhost:1025 (MailCatcher).

Both environments exhibit the same behaviour.
