[arch-general] Mutt client-Message from Gateway

[Arno Gaboury]

Dear list,

as some of you strongly advise me, I finally set up Mutt as my mail
client.
I set up with a gmail account, offlineimap and msmtp. Even if I don't
maximise the beast, everything works fine.
I still have one issue when sending or replying to this list. After my
sent, I recieved immediatly a mail
 
FROM: Gateway
SUBJECT: NDN

BODY : Your message couldn't be delivered to: kingeryj,Firstclass(The
name was not found on the remote site).

Any idea what could be wrong in my configuration?
Or maybe just an invalid adress in the list?

Thank You for help.

Regards
