Check to see if SMTP is reponding on port 25

Can Nagios test to see if an SMTP server is responding via port 25? Just something to do a HELO and validate a response...almost like a ping.

Yes.
In XI we have the
Mail Server Monitoring Wizard to make is very easy to check any or all of the following...
Ping -Monitors the server with an ICMP "ping". Useful for watching network latency and general uptime.
SMTP -Monitors SMTP service availability.
IMAP -Monitors IMAP service availability.
POP -Monitors POP service availability.

Thanks for the quick response.
For clarification purposes...does the SMTP check on Mail Server Monitor Wizard just check that the service is available, or does it shoot a request over port 25 and then listen for a response?
I'm sorry for the stupid questions, but my management is asking me and I can't find anything definitive online.
Thanks!

It checks port 25
But we do have the ability to do service checks in Nagios XI as well.
