I hope you are not permitting both the sender and recipient addresses
to be specified from a web form. In that case, your form *IS* being
abused by spammers, and you'll likely never get it off the block lists
except by changing hosts, and then in a couple of days you'll be back
on again.
1. HTML email is usually SPAM.
2. Where did you get the sender address from? That had better be
a real mailbox that actually accepts mail.
3. Hiding HTML in base64 is a much better indicator of SPAM than
just having HTML.
