There was a discussion on
gmane.emacs.gnus.general about this bug or
problem. Best probably just to check it out
there. Otherwise I had it appended to a file
and made some edits to make it more clear -
here it is

Something happened to my Gnus. Or the
remote connection?

Now when I do `gnus-group-get-new-news' Gnus
hangs until I do C-g.

The broken POP processes pile up at
`list-processes'.

Error according to socat, works with openssl.

test-zoho () { local server=pop.zoho.com local
port=995 socat - OPENSSL:${server}:${port} echo
"socat done" openssl s_client -quiet -connect

Unfortunately I don't know too much about tls,
and will be of limited help here, but my guess
is there's something slightly wrong with the
pop.zoho.com certificate, something that
openssl is letting slide, but socat and gnutls
aren't happy about.

What exactly is openssl? Can I use that instead
of gnutls?

My understanding (and again, I know very little
about these things) is that the two programs
are roughly equivalent: they handle creating
and checking TLS certificates, and creating and
handling TLS-encrypted connections to
remote servers.

I actually was just assuming you are using
gnutls, you can probably check the
libgnutls-version. You can also try setting
gnutls-log-level to 3 or 4 and fetching mail,
and see if anything interesting pops up in
*Messages*.

The bad news is that I tried this:

gnutls-cli --port 995 pop.zoho.com

And it connected just fine. You might try that,
and going through with the login procedure.

OK, then how do I specify openssl should be
used instead? Worth a shot... A search with
`apropos-value' and "gnutls" reveals

    starttls-gnutls-program "gnutls-cli"

    tls-program ("gnutls-cli --insecure -p %p
%h" "gnutls-cli --insecure -p %p %h --protocols
ssl3" "openssl s_client -connect %h:%p -no_ssl2
-ign_eof")

Neither set by me, but can be incorrect anyway,
of course. Eheh.

If you mean ... then:

    $ gnutls-cli --version gnutls-cli 3.3.8

This does, over and over again:

    gnutls.c: [3] ASSERT: gnutls_buffers.c:547

    gnutls.c: [3] (Emacs) retry: Resource
temporarily unavailable, try again. gnutls.c:
[1] (Emacs) non-fatal error: Resource
temporarily unavailable, try again. gnutls.c:
[3] ASSERT: gnutls_buffers.c:1104

Login procedure works, the rest seems fine (?).

Maybe change this variable so that only the
"openssl" string is in there?

I meant that if the variable libgnutls-version
was non-nil, it probably meant you were using
gnutls. But the variables you found above are
more relevant.

Another post on the topic:

I'm gonna use this thread to dump everything
related to this issue. At least then I have it
all in one place.

I've had the issue for several years off and
on, on several computers even with slightly
different OSs (Debian and Raspbian) so it is
starting to get embarrassing.

    Mail source (pop :user XYZ :password ABC
:server pop.zoho.com :port 995 :stream ssl)
failed: (error USER XYZ not valid)

and

    gnutls.c: [0] (Emacs) fatal error: The TLS
connection was non-properly terminated.

You're using the builtin GNUTLS support. There have been a number of
fixes to it over the years, so it could be worth trying emacs-26. If
that's not possible, the alternative is to switch to using the
external gnutls-cli command instead. Something like

(defun gnutls-available-p ()
       nil)

before you load gnus should do the trick.

Regards

Robert

OK, I'll try both suggestions and get back to
you on gmane.emacs.gnus.general !

You may also need to customize `tls-program' to use the `openssl'
command.  Although I think external-program based tls is kind of flaky,
so I don't how much you can really expect from it.

That looks like your username/password is being rejected by the remote
POP server. There may be a buffer somewhere showing exactly what the
