Thanks for reading,

	I need certain shell scripts to email me after they are done
running. I've installed ssmtp to forward to my internal SMTP server. I have
a working ssmtp config on a Gentoo system that works just fine, but on
CentOS it's not working. Here's a bounce message:

DNS does work, and I have an MX record to my internal SMTP server, even
though the ssmtp doesn't use DNS/MX records to forward email. I've also
tried turning sendmail on/off as well. Where else should I look?? A typical
command I'm using to email from the shell is this: mail -s "Test de Backups"
foo at bar.com < /dev/null ...

Any help, most appreciated!

Thanks!
