sendmail: want outgoing mail not to have sending system name

[B. Chapman]

How do I configure sendmail so that the system I am sending email from will hide the system name. Ex. system is server1.hp.com want outgoing email sent without hostname -xxxx.hp.com or just hp.com.

[Steven E. Protter]

First step:

in /etc/mail/sendmail.cf

Change:

#Dj$w.Foo.Com

to

Djwhateveryouwant

Save it

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

This will not make your mail untraceable. There will be a IP address in the log of each message accepted on the target server's mail log.

THanks.

You need to change the class of server, changing the $j will not have impact on this problem.

Edit sendmail.cf (normally in /etc/mail) and search for "CE root".

Change that entry to "CM root"

This will remove the hostname.domain and replace it with simply domain.

Note: This will only change mail from the server where the change is made. Incoming mail can not have the address changed by sendmail.

Actually, I just tried bot of the above and neither seemed to meet your criteria.
To do what you asked I changed:

# who I masquerade as (null for no masquerading) (see also $=M)
DM gumbo

Stopped and started sendmail. The mail sent came from username@gumbo after making the change.

Best of luck.
