1) You should always test plugins as the nagios user. Root has elevated privileges and you may not see the same results when the plugin is run as the nagios user.

2) It would appear that 
	a) your SMTP server is taking longer than 10 seconds to respond or
	b) you can't connect to it from that host.

>From firewall, can you 'telnet 201.x.y.3 25', see the banner, issue the 'quit' command and be disconnected in under 10 seconds (accounting for the time it takes you to type those commands)? If it's taking longer than 10 seconds and that's normal, you can use the -t parameter to increase the timeout length. Make sure that your master plugin timeout value in nagios.cfg is at least as long as what you use for the plugin though.

> I'm using Nagios v1.2 with a FreeBSD 5.4-STABLE.

What version of the plugins are you using?
