How to remove host part in the "To" field in sendmail

[Stefan Bergkvist]

Hi,

I have a hpux server that relays mail to an exchange server with sendmail.
If you send a mail from this server with eg. mailx and skip the @domain.com in the "To" field, sendmail adds @hostname.domain.com to the "To" field.
How do I configure sendmail not to insert the hostname part.
If you send mail with address user@domain.com, then sendmal doesn't apply it's host name in the "to" field.

In the sendmail.cf file is a feature to MASQUERADE AS. Search the sendmail.cf file for 'masquerade' and this will get you to the DM setting.

DMyourhost.com

This will remove the host name.

Forgot, make sure you bounce the sendmail daemon after making the changes.

sendmail is accepting the default @hostname.domain.com on the emails because it has not been told to do anything else.

There is a directive in the sendmail.cf file that will let you change it.

Djdomain.com

save the file.

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

done.

It can also be corrected in a more automated way with a sendmail .mc macro file. Let me know if you are interested in that procedure.
