Markdown sending as plain text

Certainly sounds like something which needs debugging. I'll look into it tomorrow.

Do you use the message preview, that is, does it pop up when you use Markdown?

I do use the message preview, and it always formats correctly. I only notice the problem after I send the message and see it either in my sent items or when someone replies.

I also use(d) inline CSS to do some very basic styling (which I've used for years and never changed). But on a hunch this morning, I decided to back up my preference file and start over with a clean one. Restarted MailMate and re-set up my preferred settings...and did not enable my custom CSS.

So far today, all of my messages have been sent formatted properly.

Thanks for the hint. I'll look into if this is the problem. Do you still have the setting/styling you used?

I just pasted the CSS I used, but my comment was marked as spam. Maybe you can still see it.

Happy to send you the CSS, as well as my old preference file if it helps you. Just let me know what you need.

Note that the problem has not re-occurred since my remedy above. It's working great. My custom CSS wasn't terribly important anyway. You'll probably want to choke me for doing it in the first place. haha!

I'll forgive you since it helps me find a bug ;)

Where did you configure/add this CSS?

I used: defaults write com.freron.MailMate MmDefaultCSS -string

(also note that I've been tracking/running the test builds for a while now...I think it was your general recommendation after some macOS release or the M1...I forget now.)

I am also experiencing the same issue on macOS 12.3 and MailMate 5882. I do not use a custom CSS. This started occurring on some of the latest beta releases (not sure which, unfortunately). I can see in some replies that plain text instead of Markdown formatted mail was sent, causing lists etc to not look as intended.

@cands: I believe this issue might have been fixed. Hold down ⌥ when clicking “Check Now” in the Software Update preferences pane to get the latest test release. Then let me know if it still happens.

@benny: Indeed, I confirm that the issue has been fixed since build 5884, thanks a lot!
