Hello

I am using xemacs 21.4.18 (no mule or mule), the xemacs-pkg mail-lib
1.75 with the corresponding smtpmail pkg and starttls from ngnus-0.3.

So far I have used sometimes bluebottle.com as an external smtp server
using the 25 port. This worked without problem I have added my
configuration below.

Now I tried the same for gmail. Gmail however needs tls, and in fact
with this port it works for me for mozilla. Now I tried to use the
information available for example in
http://www.pvv.ntnu.no/~terjeros/wiki/GnusGmail however when I try to
set up the relevant setting for gnus (using message-mode) or for vm
(using mail-mode), 
I am asked for my password, I type it but then 
the sending fails, with the following error
message, 
       Mechanism nil not implemented.

What is the problem? Can anybody help me?

Thanks 

Uwe Brauer
