Uhhh... something like

ereg("[_a-zA-Z\-]+\@[\.a-zA-Z\-]+\.com",$variable);

SHOULD work... If you want to make sure they're @domain.com instead of any 
domain, try...

ereg("[_a-zA-Z\-]+\@[\.a-zA-Z\-]+domain\.com",$variable);

if you want to validate e-mail address formats, there is (if memory serves) a 
discussion in the comments on php.net/eregi of how to do this best.
