From:-line in Mutt

["Sven Burgener" <maillists@bluewin.ch>]

Hi

In my yet still very empty ~/.muttrc I have the following line:

my_hdr From: Sven Burgener <svenb@bluewin.ch>

Now, this doesn't seem to do what I want: the domain I have here at home
is made up and Exim doesn't like this when it's trying to deliver a mail
I previously created with mutt:

<ERROR>
  svenb@bluewin.ch:
    SMTP error from remote mailer after MAIL FROM:<svn@hp.homelan.ch>
SIZE=1583:
    host mail.bluewin.ch [195.186.1.68]:
    501 <svn@hp.homelan.ch>... Sender domain must exist
</ERROR>

So, what part of the header needs changing so that I can mail with mutt?

Thanks
Sven
