You will have to change your /usr/lib/sendmail.cf to include a
rewriting rule that adds your domain to your sender address.  One place
you can do this is in the sender rule for the smtp mailer.  Sendmail.cf
is a hairy thing and much more than can be described in a short
message.  I can show you what I have as an example and you can look at
yours and see if you can see a similar thing to modify.  In mine, smtp
mail invokation is specified by the rule:

Msmtp,  P=[IPC], F=LmsDFMPuX, S=11, R=21, A=IPC $h, E=\r\n

You might se a rule like Mtcp or something like that.  The S=11, part
of the specification says that rule 11 is used to rewrite the sender
address.  I have a rule that looks like:

S11
# Convert sender field (From) to acceptable user@host syntax.  No
# explicit routing allowed.

R$*<@$+>                $@$1<@$2>                       If host specif, OK
R$*<$*>$*               $1$2$3                          defocus
R$*:$*@$*               $2@$3                           and strip route ifany
R$+@$+                  $@$1<@$2>
##R$+<@$=A>             $@$1<@$E.$F>
R$+                     $@$1<@$P.$E.$F>                 tack on our hostname

The last rule rewrites my address by adding my localhost and domain as
the sedning host.  The macros are defined as follows: P - primary
hostname, E - level two domain name, F - root domain name.  With my
sendmail all addresses are reformated for processing so the the host is
in "<>" and the final rewriting rule removes the "<>" focus.  Your
sendmail may be different.  But generally, what you need to do is add a
rule in one of the sender rewriting rules to fully qualify your host
name.  You might see something like:

  R$+			$1@$w

In many cases $w is your simple host or node name.  If you just
redefine w to your domain name, that will fix the problem.  At the top
of your sendmail put:

  Dwhost.domain.name

If you can't figure it out, I can send you my sendmail.cf or you can
mail me yours and I'll take a look at it.
