	Hi! 

	 When checking against a Microsoft Exchange server, that is located bwhind a 
	firewall, I get timeout.. 
	 Trying from the shell-prompt I do: 

	# ./check_smtp -H 80.199.yyy.xxx -w 20 -c 30 -t 20 -v 
	SMTP OK - 0 sec. response time, 220 domain-sbs.domain Microsoft ESMTP MAIL 
	Service, Version: 5.0.2195.5329 ready at  Sun, 24 Nov 2002 21:57:21 +0100 
	Socket timeout after 20 seconds 

	It says OK - and then timeout ?? 

	With telnet I get: 

	# telnet 80.199.yyy.xxx 25 
	Trying 80.199.yyy.xxx... 
	Connected to 80.199.yyy.xxx. 
	Escape character is '^]'. 
	220 domain-sbs.domain Microsoft ESMTP MAIL Service, Version: 5.0.2195.5329 
	ready at  Sun, 24 Nov 2002 22:00:02 +0100 
	helo ff 
	250 domain-sbs.domain Hello [195.184.zzz.qqq] 
	quit 
	221 2.0.0 domain-sbs.domain Service closing transmission channel 
	Connection closed by foreign host. 


	Any ideas ?? 

	/Brian
