Downloading mail using pop3s

[Manuel Carro]

Hello. I am trying to read mail through pop3s and gnutls-cli seems to
be able to made a connection:

gnutls-cli -p 995 my.host.com
Resolving 'my.host.com'...
Connecting to 'X.Y.Z.W:995'...
- Certificate type: X.509
- Got a certificate list of 1 certificates.

- Certificate[0] info:
# The hostname in the certificate matches 'my.host.com'.
# valid since: Wed Aug 31 11:46:09 CEST 2005
# expires at: Thu Aug 31 11:46:09 CEST 2006

- Simple Client Mode:

+OK POP3 my.host.com 2004.89 server ready
quit
+OK Sayonara
*** Fatal error: A TLS packet with unexpected length was received.
*** Server has terminated the connection abnormally.

However Gnus exits with an error:

Opening TLS connection with `gnutls-cli -p 995 my.host.com'...done
Opening TLS connection to `my.host.com'...done
Mail source (pop :server my.host.com :port pop3s :user mcarro) error (POP SSL connexion failed). Continue? (y or n)

I can read using (non-secure) pop3. Is there any way to snoop what the
gnutls-cli is doing, to try to isolate the problem? Thanks!

You can trace through the functions that the
mail-source-{check,fetch}-pop functions call. I'm not sure what's
wrong, but I would try the :program option to make sure a direct call to
gnutls-cli works and then use :port to indirectly call it.
