[Mimedefang] SPF and really stupid mailers

[WBrown at e1b.org]

This morning, I had an issue come up with a customer involving 
Hallmark.com trying to send a greeting card through our filters. 
Apparently Hallmark uses the email address of the sender as entered on the 
web form as the SMTP  Mail From: data.  That's all well and good until 
someone uses a domain like Adelphia.net who has an SPF record that says 
"-all".  General practice is to add 5 points for SPF hard failures like 
this, so the message eventually bounces.

I explained what happened to the customer, and he accepted it, but i'm not 
sure about the end user. (She was sending the card to herself.)  Those 
e-cards always struck me as a bit lame anyways...

Anyways, my question is how do you all handle stupid mailers like Hallmark 
when users complain about them getting blocked for poor email practices.
