Bill (and others),

I noticed that your latest toaster patches include support for DomainKeys. I've just read the informative Wikipedia article on DK <http://en.wikipedia.org/wiki/Domainkeys>, but have some questions on how you are using DK.

One of my clients had a recent email from PayPal get tagged as spam, and I noticed in the headers that PayPal is signing their outbound email. What will I gain by updating my qmail-smtpd with DomainKeys support? Will it only accept properly signed messages? At that point, do I enable some rules in SpamAssassin to give preference to signed emails? Will I need to someday create and manage a list of blacklisted domains that use DomainKeys?

I understand the benefit of signing outbound mail, but I assume that I would be signing all messages with my domain name, and not the virtual domain of each customer. Has anyone explored a method of creating keys for each domain hosted, and signing based on the domain of the authenticated (SMTP AUTH) sender?
