	The "SRHN" is used when you don't use your Cobalt as your 
	main SMTP server. For instances assume that you are an
	ISP you will already have a powerfull SMTP server in your 
	domain network, right?? Now in order to supervise and regulate
	the e-mail traffic across your network you can specify
	within sendmail that all the mails coming from your 
	Cobalt should first go to the Main SMTP server. Read
	O'reilly's Sendmail bible.

	The standard sendmail configuration makes a reverse lookup.
	you'll find a file in /etc/mail where the name of your
	local cobalt server is specified. In addition to this you
	should add the Fully qualified domain names off all the sites
	you are running using ssl, since ssl requires a separate IP,
	and will cause the reverse lookup to fail, if you don't specify
	the correct answer to sendmail

That's all there is too.
Reading your log files can tell you a lot .
