Suppressing error from displaying

["Ron Piggott" <ron.piggott@xxxxxxxxxxxxxxxxxx>]

I am using this syntax to check for a valid e-mail address

list($userName, $mailDomain) = split("@", $buyer_email);
if (checkdnsrr($mailDomain, "MX")) { 

if no domain is provided ( ie e-mail address is something like âronâ with no @ ) the following error is displayed:

Warning: checkdnsrr() [function.checkdnsrr]: Host and type cannot be empty

Can I suppress this from displaying so *just* my error message displays?

Ron
