smtp problem

[click@gmx.net]

Hi,

I'm new to Wanderlust and not a an meacs pro as well (I'm proficient  
enough to navigate safely but no lisp knowledge at all)
I set it up according to  
http://emacs-fu.blogspot.com/2009/06/e-mail-with-wanderlust.html
Reading my maildir works, but I can't send through wl's smtp client.
I'm pretty sure everything is set up correctly, as I have a working msmtp  
client for mutt with the same settings. The only thing that bothers me is  
that I have to set a tls certificate in msmtp which I have not found how  
to do this in wl.
I do not use gmail, but I registered an account there just for testing  
purposes with wl. But I also can't get gmail with wl working either,  
although I found a guide for this as well and I'm pretty sure settings are  
ok.

Is there anything I have to do before using wl? Any special .emacs  
settings?
Is it possible to use msmtp in wl like mutt does?
