in account web page, allow user to configure rulesets for delivery

for example, by matching incoming messags on smtp mail from, verified domains
(spf/dkim), headers. then delivering to a configured mailbox. for mailing
lists, if a verified domain matches, regular spam checks can be skipped.

this was already possible by editing the configuration file, but only admins
can edit that file. now users can manage their own rulesets.
