How to hide Server Name in the domain name when sending an email using sendmail on SCO unix

When I send email using the command line to one account in the same server it's not hiding the server name on the domain section, why ? Here's an example :

# mail henry
Subject: test
test
.
EOT

> > >and here is the message received :

From: root@vxgxnx.net (Superuser)
To: henry@atksco1.vxgxnx.net
Subject: test

How can I get rid of that atksco1 ?

thanks

Open your sendmail config file /etc/mail/sendmail.mc:

# vi /etc/mail/sendmail.mc

Append/add/modify the lines as follows:

MASQUERADE_AS(vxgxnx.net)dnl
FEATURE(masquerade_envelope)dnl
FEATURE(masquerade_entire_domain)dnl
MASQUERADE_DOMAIN(vxgxnx.net)dnl

Save and close the file. Update and restat sendmail server:

# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
# /etc/init.d/sendmail restart

I checked the sendmail.cf file and it already has those settings, please look below, do I have extra lines that I should have ? thanks

You only need the MASQUERADE_ENVELOPE feature and the MASQUERADE_DOMAIN. Also it shouldn't be in the LOCAL_CONFIG section, try this setup:

divert(0)dnl
VERSIONID(`@(#)opensrc:src/sendmail/patches/cf/cf/sco.osr6.mc /main/uw714mp/11')dnl
OSTYPE(sco.osr6)dnl
DOMAIN(generic)dnl
define(`confDONT_BLAME_SENDMAIL',`groupwritabledirpathsafe,linkedaliasfileinwritabledir')dnl
FEATURE(`access_db',`hash -T<TMPF> -o /etc/mail/access.db')dnl
FEATURE(`use_cw_file')dnl
FEATURE(`always_add_domain')dnl
define(`confDOMAIN_NAME',`vegena.net')dnl
FEATURE(`masquerade_envelope')dnl
MASQUERADE_DOMAIN(`vegena.net')dnl
MAILER(local)dnl
MAILER(smtp)dnl

Still not working, after reseting the P86sendmail stop / start script, I'm still seeing the atksco1. this only happens when the email gets generated from the command line, If I use thunderbird/outlook to send an email to a SCO user it gets it perfectly. Any other idea ?

amolg, still not working after commenting out the:

FEATURE(`allmasquerade')dnl

jar3817

Instead of doing this:

# mail henry

Try with a full email address:

# mail henry@vxgxnx.net

It worked that way, so there is no way of avoiding to type in all the domain name ? (i.e. @vxgxnx.net ) ?
