I think all you need to use is the check_smtp thats already a part of Nagios. It will check any IP or domain name to see if the SMTP port is open and accepting traffic.<br />
<br />
If the hosting provider suspends the account and blocks email. The check_smtp will alert you the SMTP is down

That is what I am trying to figure out, but my configuration must be off a little.<br />
<br />
I may have found my typo. I am testing now.

Can you do a check_smtp to an email address instead of a host?<br />
Thanks,

I am trying to setup Nagios to monitor SMTP traffic flow for an external domain (One of my clients).<br />
<br />
My Goal is to get an alert if SMTP traffic is not passing every so often to their SMTP server. <br />
We had a client who had hosted email through a different solution provider, that inadvertently suspended their account, and they didnt notice it for 5 hours, and were curious why we didnt notice their hosted email solution was not receiving mail.<br />
<br />
I am curious if anyone has any information on how to obtain this. I literally just setup nagios for the first time today and believe it can work but am having trouble.<br />
<br />
Thanks in advance.

Monitor SMTP delivery with Nagios

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.
