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: Date: Thu, 13 Jul 2006 13:33:22 -0700 From: Mail Delivery Subsystem <MAILER-DAEMON at backups.amgt.com> To: <root at backups.amgt.com> Subject: Returned mail: see transcript for details Auto-Submitted: auto-generated (failure) [-- Attachment #1 --] [-- Type: text/plain, Encoding: 7bit, Size: 0.3K --] The original message was received at Thu, 13 Jul 2006 13:33:22 -0700 from backups.amgt.com [127.0.0.1] ----- The following addresses had permanent fatal errors ----- <admins at amgt.com> ----- Transcript of session follows ----- 550 5.1.2 <admins at amgt.com>...

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! Mark Schoonover IS Manager American Geotechnical V: 858-450-4040 - F: 714-685-3909 - C: 858-472-3816
