Banning e-mail addresses in formmail

can you ban e-mail address from submitting formmail forms?

[silentmikedotus]

I have done quite a bit of research on this, but still have come up empty: is it possible to ban certain e-mail addresses from being input into a formmail form?

For example, if I were to want to ban all yahoo.com addresses, and a user put a yahoo address in the form, could I prevent them from submitting it? Or, could I submit a certain address, such as [e-mail]?

Any help would be appreciated. Thanks in advance!

I'm no expert on this, but have a look at the London Perl Mongers version of FormMail, which seems to be a lot more secure and easier to customise...

@banned = ('.*@yahoo.com','.*@hotmail.com');
$banned = 0;

foreach $b (@banned) {
if ($qs{'email'} =~ /$b/i) {
$banned = 1; last;
&error('Email Address Banned');
}
}

Note the .* is "any email" @yahoo.com, etc.
