[Nagiosplug-devel] Recent patch to check_smtp.c

[Subhendu Ghosh]

I guess one could add a regex to see if the initial 220 response matches 
some thing unique to Exchange..

Could you post a 220 response from an Exchange server - I am happily 
ignorant on that issue :)

Also if this is causing you problems right now - just change the 
SMTP_USE_DUMMYCMD to 0..
