Okay if you just want to do a REGEX something like
ereg("([_a-zA-Z\-]+|\*)\@[\.a-zA-Z\-]+\.com",$variable);
should work, but test it. I'm not 100% the wildcard part will work.
If you want to make sure the domain is valid, well that's much more fun ;)...
function validateAddr($addr)
{
/* UNTESTED- whipped together in about 2 mins, so test before use */
if ( !ereg("[_a-zA-Z\-]+\@[\.a-zA-Z\-]+\.com",$addr) )
{
exit("eMail address format invalid.");
}
else
{
$host = explode("@",$addr);
$host = $host[1];
if ( !getmxrr($host, $array) )
{
exit("Invalid eMail address- domain $host does not exist...");
}
}
}
I hope your eMail client doesn't wrap that. If it does eMail me and I'll send
you a text file. Meanwhile, it is untested so test before use.
If you want to get really in-depth, you could try to send $host:25 EXPN or
VRFY requests, but they SHOULDN'T respond to those so I wouldn't do that if I
were you.

Nobody realizes that some people expend tremendous energy merely to be
normal.
