[Xymon] smtp test oddness

[Joe Acquisto-j4]

xymon 4.3.7

Sometimes on smtp test I see:

-----
Service smtp on mail2 is OK (up)

220 SMTP Proxy Server Ready
500 Command unrecognized:  mail
221 Service closing transmission channel closing connection

Seconds: 0.00
------

Other times I see:

-----
Service smtp on mail2 is OK (up)

220 SMTP Proxy Server Ready

Seconds: 0.00

-----

All seems to be fully functional at the other end.
