Yes. There are two other options you can use. 1) Just check that the server 
answer on the port and not run the protocol (smtp) test or 2) use send/expect 
which allow you to send whatever you want to the server 
( I.e.

    if failed host port 25
       expect "^220.*\r\n"
       send "ELO localhost.localdomain\r\n"
       expect "^250.*\r\n"
       send "QUIT\r\n"
       expect "^221.*\r\n" 
    then alert
