CDO Issue With Badmail

Usually when I setup a web form with CDO I either set the "From" field
in the email to either:

1. The email address of the person filling out the form, in which case
user errors often result in the mail getting stuck in the badmail folder
and not being sent

2. An alias for the client (like Join Bytes!) to guarantee that it
gets delivered, but this is less convenient for the client as they can't
just reply-to the message, they have to manually change the address (not
a big deal, but annoying)


Is there another way to guarantee that even with a bad "from" address
scenario #1 will work every time? Or some other option I'm too dense to
have realized?
