I felt the same way . The idea came when I tried to submit patches to sourcehut using my gmail account and the gmail smtp gateway didn’t work (connections, formatting).

A quick proof of concept with the REST API and I thought – why don’t we all use this for patches?

I would be surprised if has not. There have been lots of tools over the years where the idea was to present a command-line interface compatible with Sendmail's message submission mode, and hand the mail over to a smart host, possibly not using anything like SMTP.

I predict that someone will be asking for the -t option to be supported here. (-:

i got the idea because gmail smtp didn’t format patches properly. It uses mime and rich formatting which breaks patches.

REST apis preserve the original message .
