hmmm - I was thinking that if the connection were refused, the result
would be 0 (failure) - I could be wrong, I've been wrong once or twice
before ;-)
I cannot fathom a way that you could ping or telnet into the box with
any predictable outcome to know that mail is being refused on port 25
(which is what he is looking to get alerts for).
My previous recommendation for webmin which already includes a postfix
monitor seemed to fall on deaf ears.
