Sendmail

I have a small Linex / Windows network running tcp/Ip.
I have a functioning DNS but as of right now, I'm not on
line. However, the DNS is working..e.g- no problems re-
solving names on the windows machines.
Everything seems to be working except for...!! For some
reason, I must INCLUDE THE HOSTNAME OF MY MAIL
SERVER everytime I send mail to a user. I have, or at least
I think I set it up correctly in DNS, and even added the
DMmctcompany.net  line in 'sensmail.cf'
Also, when I exclude "mail" <----that is the name of my mail
server... from the  IN   MX   10 mail   line in  named.hosts,
my server still will not except anything except:
username@mail.mctcompany.net
The mail does get there, however it gets kicked back to
root/postmaster <---e.g.me
This is about the only thing that didn't work out for me, and
it should have!!
I'm setting up a small Internet Site, and have been working
with Linux for a little over a month. I would like to work out the bugs before going on line.
Any Help would great!!


Thanks!!

For 20points the best advice I can get is to get the Orielly and Associates book  "Sendmail".  Other than that...  start from scratch your sendmail.cf file is VERY particular.

Enjoy,

It looks like you have to tell sendmail to accept mail
for yourcompany.com. Defaultwise, sendmail only accepts
mail for your.host.name. Usually, there exists a macro
defining a list of hosts for which sendmail accepts mail.

Add in the following lines into your sendmail.cf:

Fw/etc/sendmail.cw

Add in your domain name (and any other domains you
want to accept mail for) into the file
/etc/sendmail.cw  
(It's just a text file you create with a list of domains on each line)


Hope this helps.

Well, What does your MX line in DNS look like?
is it :
companyname.com      IN       MX     0 mail.companyname.com ?

and is Sendmail using DNS?
