SMTP port 8025 Service Description help

Nagios Nagios Configuration support

Hello,
My SMTP service runs on port 8025 instead of the standard ports 25/443.
How do I tell Nagios to check SMTP on port 8025?

currently:

service_description SMTP

Nagios reports, CRITICAL failure.

tfyt,
d

also is there somewhere that lists all of the std service_descriptions for Nagios?

if I had only searched for an extra 10 mins…

./check_smtp --help
service_description SMTP -p 8025
