I guess you're talking about this wiki page:
https://wiki.debian.org/msmtp
I've just reviewed it and updated it with a few improvements.

I don't know why you think I could particularly help you on msmtp, I
don't use it (I use mpop though).
I *think* you can discuss your issue on debia...@lists.debian.org (I
have added it in Cc), to which I suggest you subscribe. Another
possibility, if you are quite sure that there is an software issue
behind this, is to file a new bugreport (with e.g. the "reportbug" tool)
targetting the software you think is the culprit.

These error messages are insufficient to understand what's wrong. Is it
all?
I suspect the process which "mail" talks about is in fact
/usr/bin/sendmail, which resolves as one of the msmtp programs; you can
check that by following the /usr/bin/sendmail symlink, and by using
strace to see which child process of "mail" is the cause of this error
message:
strace -e trace=process -o /tmp/strace.log mail -s ...
If I understood correctly, there is a msmtp daemon running somewhere.
Have you looked at its logs?

I think uninstalling mailutils is a bad idea here.

Hi all!
Thanks Fabrice, for your thoughtful reply and for forwarding the question here.
Replying below with more details about the issue:
> I guess you're talking about this wiki page:
Yes, and thank you for the improvements
> These error messages are insufficient to understand what's wrong. Is it
> all?Yes. Anytime I try to use the "mail" command this is the message I get.The first time after a reboot, I also get a keyring prompt. This happens because of the configuration .msmtprc (auth login).
>I suspect the process which "mail" talks about is in fact>/usr/bin/sendmail, which resolves as one of the msmtp programs; you can>check that by following the /usr/bin/sendmail symlink,
the /usr/bin/sendmail symlink points to "../bin/msmtp"
Also,
usr/bin/mail > /etc/alternatives/mail
usr/bin/mailx > /etc/alternatives/mailx
And these both point to /usr/bin/mail.mailutils

Please see strace.log below
> If I understood correctly, there is a msmtp daemon running somewhere.> Have you looked at its logs?
No logs related to the daemon found in /var/log/ (tried mail, err and logs, daemon logs, messages), what is the usual location? I think it probably isn't related here.

I have the feeling that unfortunately the root cause of the initial
problem (it works with bsd-mailx but still fails with mailutils,
correct?) remains a mystery though.
Maybe you would like to help investigating the issue, in which case we
could discover and fix a bug, so that the issue doesn't hit anybody else
in the future, which is good for the community. If you would like to do
that, there are things we can do to investigate, such as enabling msmtp
logging with:
logfile -
Which would allow to see the actual error message. See
https://marlam.de/msmtp/msmtp.html#Logging
But don't feel obliged to do that. It's OK. I have updated the wiki
page with your inputs anyway.
Thanks!
