Nagios Support Forum

Hello,
We have not received any email alerts for nagios since 9/26/2017. I ran the System Test Email Messages, and I took the error below. Can you help me, has anyone seen this happen?

A test email was sent to [email protected]

An error occurred sending a test email!

it would appear you're having issues connecting to the SMTP server. is 'smtp.generali' the correct FQDN?

can you probe the mail server's port from the Nagios machine?

Hello,

Is this the test you requested? If yes, it seems that smtp.generali 25 is functional. I need to solve this problem soon! Do you have any other ideas?

[root@GMZ4AP21 tmp]# telnet smtp.generali 25

On the Admin -> Manage Email Settings page can you check the box for "Debug Log"
Then perform the test again.
