This is not a good idea. What you must do instead is to restrict accepting
relay attempts (that is, sending mail from [EMAIL PROTECTED] through your machine, to
any other domain but those you control)
Hmmm...
suresh@mjollnir:~> telnet mail.jobpartners.com 25

This strongly suggests that you have configured sendmail using linuxconf.
Throw that .cf file into the dustbin and regenerate a new sendmail.cf from the
/etc/sendmail.mc file (or it may be in /etc/mail in some versions)
For this you have to install the sendmail-cf-[your-version-number].rpm from the linux
CD
See http://www.orbs.org/otherresources.html for more information (and see
http://www.sendmail.org/faq/ - that will answer 99.999% of the sendmail
questions I see posted here - this "open relay" is one of the top 5 questions
answered in that FAQ)
