I am getting an error from my ISPs SMTP server when trying to send emails via MIME::Lite.

The error reads "relaying mail to yahoo.com is not allowed"

Rather than annoy my ISP (well more than usual) can I use another mail module ?

I know about mail::sendmail, mail::bulkmail, net::smtp, mail::send, mail::mailer but dont know which one to use!

I have a mailing list and want to send customised emails to about 500 people in one shot. I'm using Perl on a Win98 if that matters.

cheers,
Digsy
