Have you verified that you are not on a blacklist or that your emails are not being sent to spam. Yahoo and hotmail, are pretty notorious for just blindly rejecting mail if the domain is not valid or if the IP is on a blacklist. You might also verify that your provider has not disabled you from sending out on port 25.

Hello
Before leaving I receive yahoo emails from nagios and now I get nothing, I tested with a mail server that I have in the company and it does not matter.

Check the /etc/mail.rc file. What server are you using to send email with? --- Can you send email from the CentOS system? You might try running the line below and see if you get the email.

Code: Select all

 /usr/bin/printf "%b" "*****Nagios Test*****\n\nThis is a test" | /bin/mail -s "****Nagios Test****" [email protected]

If you don't get an email when you run the command manually, the problem is because your CentOS system isn't properly configured to send email or someone else along the line is blocking the email (Maybe for an invalid from domain?).

Spot on. Thanks for the input.

@OP: What were the results of MLaing's suggestion?
It may also be prudent to check your mail logs:

Code: Select all

tail /var/log/maillog

That tail of the maillog just shows the [email protected] address, not the yahoo one. Could you post a bigger tail of the maillog (in code wraps)?

Code: Select all

tail -50 /var/log/maillog
