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@bar.com < /dev/null ...

Any help, most appreciated!

I know very little about this, but in my little niche, I found I had to update sendmail.cf to not be restricted to localhost.

In /etc/sendmail, I updated sendmail.mc:

# pwd /etc/mail # diff sendmail.mc.bak sendmail.mc 105c105 < DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl ---

dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

#

Then ran

make -C /etc/mail

as shown in the .mc and .cf files.

This allowed intranet mail to work here.

Thanks!
