Temporary Return-Path check #103

Closed Halyul closed 6 months ago

Halyul commented 6 months ago

Hi, recently I have encountered an issue where the email is being rejected due to the presence of Return-Path in the email.

I'm using Zitadel which sends out email with Return-Path in the headers (their code).

I noticed that mox rejects emails when Return-Path is presented. I'm wondering if mox can provide an option to disable this check.

I know complying with RFC is a good practise, but getting it resolved on Ziadel side is much harder. Nevertheless, thanks for your hardwork!

hi halyul, thanks for the report. Indeed mox is being too strict and not very helpful here. I've changed the check so it only triggers in "pedantic mode".

Thanks for your fast response! Looking forward to the new version!
