hello
I tested the sending of email I added the following to the file localhost.cfg
define service {

use local-service
host_name localhost
service_description SMTP Response Check
check_command check_smtp! 5-t-e "my email address"
}
but I like error: Invalid SMTP response received from host: 220 ESMTP Exim 4.72

The -e that you're giving it is the expect string, which you are telling it is "my email address", but its returning "220 ESMTP Exim 4.72". Try defining the command as follows:

I tried with this: he displays a warning: Invalid SMTP response received from host: 220 "my_email_address" ESMTP Postfix (Debian / GNU)

The -e whats tripping you up in this command. When the plugin connects tot he mail server, the string its expecting is "my_email_address", and its getting a the wrong string back in return.
