check_pop

[Russell Scibetti]

Yes, true.  Hence why the check_tcp knows to use port 110 when check_pop 
is the command used.  But I am concerned about the expect string.  I 
don't understand why the expect is set to "110" as opposed to expecting 
"+OK", which is the standard FTP response when everything is working. 
 There are times you get a 110 back when FTP isn't responding, as we 
unfortunately just discovered here.
