Sendmail sending mail as localhost.localdomain

[ggggus]

Setting up a server, and the machine identifies itself everywhere as localhost.localdomain

First, is there a way to blanket change this everywhere do a fully qualified domain like piercedmedia.com?...and is this advisable?

Here's my immediate problem...
I'm getting mail returned like this:

The original message was received at Thu, 16 Mar 2006 08:31:29 -0600
from localhost.localdomain [127.0.0.1]

   ----- The following addresses had permanent fatal errors -----
<info@somedomain.co>
    (reason: 501 Your domain does not seem to be valid. Could not find MX record
for your domain.)

   ----- Transcript of session follows -----
... while talking to mail.somedomain.com.:
>>> MAIL From:<apache@localhost.localdomain> SIZE=1383
<<< 501 Your domain does not seem to be valid. Could not find MX record for your
domain.
501 5.6.0 Data format error

I think that the problem probably has something to do with this line in the M4 config file:

LOCAL_DOMAIN(`localhost.localdomain')dnl

But I'm not sure how I should change it, the server is running about 20 virtual hosts on apache and many of the sites need to send mail out as themselves...should I add multiple lines for each virtual host?

There should be a sendmail cf file that you can edit to change the local domain and then you have to re-run the m4 hash on the cf file. Sorry, I dont' remember the exaxct steps, it has been several years.

Secondly, verify that the server itself has a domain name.

Type hostname from the command line and see if you get localhost.localdomain or do you get a fully qualified domain name.

If you are not getting a FQDN, then first fix that. Edit the correct files (depends on your distribution) and /etc/hosts files. Once you get your hostname fixed then go after the sendmail config.
