Simple "mail" thinks I'm at localhost.localdomain

Using simple "mail" in a script, it says I am
"(E-Mail Removed)" (and the relaying system is rejecting the
message) even though all other facets of the networking software appear to
be properly configured. I wrote a couple of quickies and verified that
gethostname(2) and so forth are all returning the configured values, not
"localhost.localdomain".
One final clue: I can use "nail" (not "mail") with a "-r
(E-Mail Removed)" (using the correct values) and get the relay system to
accept and forward the message.
Anyone know where "mail" gets the host's name and domain? ("nail"
will do the same if I omit the "-r (E-Mail Removed)" option.)
Thanks!

You need to configure sendmail properly. In your sendmail.mc file, somewhere
_above_ the MAILER() definitions:

MASQUERADE_AS(`host.com')dnl
FEATURE(`masquerade_envelope')dnl
FEATURE(`allmasquerade')dnl

Rebuild the sendmail.cf file and restart sendmail. Please see
http://www.sendmail.org/m4/masquerading.html for further information, as
well as reading the cf/README in your distribution.

Mail doesn't know anything about it, sounds like your MTA for any
further help, you need to tell us which one you run or even
better repost with full information to the proper ng
comp.mail.sendmail, if you are running sendmail.

Thanks Tony, that did it. I was not aware that "mail" is *supposed* to say
the message is coming from "(E-Mail Removed)" and that the
MTA (such as sendmail) is going to be doing the rewriting (as a
masqueraded host) so my "blame" of "mail" for the problem was wrong. Lucky
for me you understood my problem and gave the correct solution.
Thanks again for your right-on answer!
