Eh, I'd have to re-read the docs. As a hunch - search
/etc/mail/sendmail.mc or equivalent for "MASQUERADE" - if anything is
enabled try to comment it out, regenerate sendmail.cf, restart the
service.

Another hunch: see if there is any *.rpmsave file that CentOS 5.6
might have kept around after clobbering your configuration (if that's
what it is).

For the future, I try as much as I can to keep stuff like that under
version control, so that if anything gets corrupted I can restore.
