Well. something like 

if (!eregi("^[A-Za-z0-9\_-]+@[A-Za-z0-9\_-]+.[A-Za-z0-9\_-]+.*", $email)) {
echo "$email doesn't seem to be a valid e-mail address!"; 

would do the job. Of course, that doesn't stop people from entering a false
email address. You could do a DNS-lookup to see if the domain-part of
the address really exists, too.
