"reply to this email to respond" stopped working

In the past, I have been several times successful with "reply to this email to respond". But, recently, this seems have stopped working. Latest example: Today I got the message:

I have successfully migrated to Zope 4 and now the real nightmare begins: Migration to Python 3.

Look again at `zodbupdate`. Find the parameters affecting
the translation from Python 2 `str` to Python 3 `str`
and use them to get most Python 2 `str` objects into Python 3 `str` objects.
`zodbupdate` may occationally do too much in this respect, but the
cases are likely rare.

But, this message has not yet (4 hours later) reached the forum.

Unfortunately, the "reply to this email to respond" function seems very fragile.

Hi Dieter - it never arrived?

It never arrived.

I don't know how I could track this down. There is an admin panel here that shows email received, bounced, and rejected. In "received" it shows the last email from you to be from November 29 (!). Nothing shows in "bounced". In "rejected" we have quite a few but none from you, and most are from attempts @fulv and I made to get Stack Overflow to send emails to our forum to post questions (we also tried via IFTTT, but we ran into blockers).

Has the feature stopped working for you entirely?

I used it recently, successfully, here: Running Plone Docker image on Windows and it shows in the "received" list of emails

Thank you for looking into this!

When I noticed that it does not work reliably for me, I reverted
to responding via the internet site. Thus, I do not know.

I respond again to this post via email. Let's see whether it arrives.

It did!
