Web forms and POP before SMTP on BQ CentOS

[cybercytes]

I'm trying to get my old HTML forms script (perl) to work with POP before SMTP.
Can anyone show me a snip that will authenticate a script to BQ's POP before SMTP?

I've been unable to make the following work.

use Net::POP3;
my $pop = Net::POP3->new($host);
$pop->login($username, $password);

Thank you
