[Mailman-Users] Mailman just doesn"t send the messages... :-( SOLVED

[Laurent Lesage]

Hi Mark,

I tried the "debug session" as you told me to do. I had exactly the
error reported in the fisrt link you gave (

See http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.014.htp

)

So, i went back to the "hostname" : in fact, as I told, my machine is 
not his own DNS server. And I didn't put the name of the machine 
(/etc/hostname in Debian) in the /etc/hosts file. It was in it, but 
fully qualified (serveur.lesagepono.be). I just add "serveur" in the 
/etc/hosts at the address of my machine and that's it! Until now, it 
didn't have any problem with those "messy" names on my server. I should 
configure myself a good DNS server... So it seems that the python 
routine (or the standard smtp routine??) just look if the `hostname` is 
reachable. It doesn't try to resolve the name "localhost" with 
/etc/hosts, but use only the hostname defined on the machine. I'll have 
to RTFM ...

Thanks a lot to you, Mark, for your quick answers, moreover during the 
weekend!
