Linux.com is a domain registered to Infomagic.  So unless you run your own
internal DNS server all your mail is probably going to mail.linux.com
(193.79.73.114) and they are rejecting it and you get a bounce back.  There is
probably no problem with sendmail.  But DNS (aka bind aka named) and sendmail
operate in very close co-ordination so it is often hard to tell who/which is
causing a mail delivery problem.

Try doing a "sendmail -v JoeUser@mylinux.linux.com" then press enter period
enter and watch and see who sendmail tries talking to.  I'll wager it's not
your machine.
