Yes, or something that does the same thing. You may just need to start  
the sendmail service. Most modern distributions have it installed by  
default and ready to listen for requests from localhost; you may have  
just turned it off. In every case though, if you're going to be  
sending e-mails to a server that is off your network (like  
networksolutionsemail.com), you need to ensure that your nagios server  
follows expected standards for sending e-mail -
	- has a valid reverse DNS entry for it's public IP (1.2.3.4 ->  
nagios.your.domain)
	- that name you give it resolves back to that same IP  
(nagios.your.domain -> 1.2.3.4)

Nagios itself doesn't send e-mails and depends on an external program  
like sendmail to do so. If you don't want to configure sendmail, there  
are a couple alternatives listed in this FAQ --
