error 552 when sending a patch via hg email. Anyone else?

[Antonio Muci]

Hi list,

I am trying to send a patch with my usual setup, which has beenthe same
for years: "hg email", with the following setup in thg/.hg/hgrc:

$ cat .hg/hgrc
[smtp]
host = XXX
port = YYY
[...]

[email]
from = Antonio Muci <a....@inwind.it>
cc = a....@inwind.it
to = thg...@googlegroups.com

However I get this error now:
abort: (552, b'Message contains bare LF and is violating 822.bis section
2.3')

My hg version is 6.5.3. I guess this matters, too, because hg email is
an extension bundled with mercurial.

I suppose the error is raised by the googlegroups SMTP server.

Nothing else (notable) changed on my side: same setup, a short one-line
patch with 30 lines commit message etc.

Is anyone having the same problem?
Are there any alternatives for sending patches? Heptapod maybe?

Thanks
Antonio

I didn't have a problem with emailing through thg the last time I did it- it looks like a couple of months ago.  I've been busy with work, but I'm sure I'll need to send more patches at some point for Qt6 and arm64 on macOS.

Maybe try pushing a topic to the repo, and send a link to the mailing list?  I'm not sure why MRs are disabled on the repo, other than the ML is traditionally how it's been done.
