My naive solution is to use a program like pine and configure
host name to the domain of your email address.

There is apparently a dirty solution involving reconfiguring sendmail.cf
file but so far it has not worked for me yet.

I myself am looking for a way to do all this at the shell prompt
sine I need to a program to produce various messages in a script and
then send them out periodically. This program will be used by
many users with various email addresses/domains from my
linux box and I am hoping that all will be well.

Hi

I guess this has got to be a really common probem - but I can't sort
it out...

I'm using linux as a single user and I'm getting mail (and news) from
my ISP with fetchmail (and Leafnode). That's OK.

But when I send mail most recipient serves bounce it with a:

<<< 553 macforce.sumus.dk does not exist

Two headers are required:

Hey, thanks - it seems to work!

And the other thing I was asking about (which nobody answered) - I
found out myself - after reading all the posts I could find in this
and a couple of other NGs saying something about masquerading :-)

The answer was that since I have dynamic IP with a constant hostname
registered with my ISP I'm to say
----
# my official domain name ... define this only if sendmail cannot
# automatically determine your domain
#Dj$w.Foo.COM
Djmyhostname.myispdomainname.dk
----
in the .cf - so it really wasn't about masquerading :-0

I'm happy again! - just wanted to let y'all know...

This will work, as long as you do not include attachments.
