It dependes on what you are trying to acheive.

For example, today I have emailed a number of abuse@ mail addresses because a number of IPs have been attempting port scans. For this purpose I used whois and host - Sam Spade will also perform the same tests for you.

However if you want to mail the person at that IP address this presents a number of problems.

The address may not be that of an individual, but may be the address of the internet router that is providing NAT routing for a network. If you use whois to find out who owns the IP you could then mail postmaster@.....

You could test to see if that IP is running a mail server by using telnet a.b.c.d 25 and see if you get a reply - if so you should be able to send mail to postmaster by pointing your mail client to the ip address but this is not an entirely legitimage method for delivering mail.

What are you trying to acheive?
