Email Delivery

[tgriep]

Without knowing what OS and release the SMTP server is running an what mailer daemon it is running, I cannot specify the log files to check on it to see why the plugin cannot login to the server to send emails.
If the SMTP server is running Linux as the OS and either Postfix or Sendmail as the mailer daemon, the log file is typically here /var/log/maillog but the Server admin should know where it is.

You can try and just run the check_smtp_send part of the plugin with verbose enabled and maybe it will show something. Problem is that the plugin may not return debugging as you are using TLS and the TLS perl module does not have debugging capabilities.

Code: Select all

/usr/local/nagios/libexec/check_smtp_send --hostname xx.xxx.xxx.xxx --tls --username xxxxxxx --password xxxxxxx --port  --mailto xxxxxxx --mailfrom xxxxxxx -vvv

To be clear, you logged in to the server and saw the email that was sent, correct?

It looks like the SMTP server does not require TLS so you can drop the following option from the check_email_delivery command

Code: Select all

--smtptls

Try running the command like the following example. If it works, update the command on the Nagios server and you should be good to go.

Code: Select all

./check_email_delivery --mailto xxxxxxx --mailfrom xxxxxxx -H xx.xxx.xxx.xxx --smtp-server xx.xxx.xxx.xxx --smtp-username 'SYSVWUKDIS' --smtp-password 'xxxxxxx ' --smtp-port 25 --imap-server xx.xxx.xxx.xxx --imap-username 'SYSVWUKDIS' ---map-password 'xxxxxxx ' --imap-port 143

If not, we just have to figure out the what the IMAP server needs to login.

In your example, you added the --download option which requires the Email::Simple module to be installed on the server.

Code: Select all

cpan -i Email::Simple

Try this command for TLS

Code: Select all

./check_imap_receive -H xx.xxx.xxx.xxx -U xxxxxxx -P xxxxxxx --download --download-max 50 -s SUBJECT -s 'test message'

If the server requires SSL, run this

Code: Select all

./check_imap_receive -H xx.xxx.xxx.xxx -U xxxxxxx -P xxxxxxx --download --download-max 50 -s SUBJECT -s 'test message' --ssl

If the IMAP server required TLS, run the following example should work.

Code: Select all

./check_email_delivery --mailto xxxxxxx --mailfrom xxxxxxx -H xx.xxx.xxx.xxx --smtp-server xx.xxx.xxx.xxx --smtp-username 'SYSVWUKDIS' --smtp-password 'xxxxxxx ' --smtp-port 25 --imap-server xx.xxx.xxx.xxx --imap-username 'SYSVWUKDIS' --imap-password 'xxxxxxx ' --imap-port 143

If it needs SSL, run this

Code: Select all

./check_email_delivery --mailto xxxxxxx --mailfrom xxxxxxx -H xx.xxx.xxx.xxx --smtp-server xx.xxx.xxx.xxx --smtp-username 'SYSVWUKDIS' --smtp-password 'xxxxxxx ' --smtp-port 25 --imap-server xx.xxx.xxx.xxx --imap-username 'SYSVWUKDIS' --imap-password 'xxxxxxx ' --imap-port 993 --imapssl
