Bug 158756

If I use the spam-wizard to set-up spam-filtering via bogofilter, the "check-rule" only includes "email not larger than x". Since kmail provides a whitelist-feature, i.e. "not in addressbook", this should be added as criterion.

If this is not enabled by default because checking against every single contact in all addressbooks is too slow, I would suggest the following, if it is doable with akonadi. There has to be some possibility, since thnderbird can do this as well.

If one would create a sub-list of just the domains that are in the local addressbook, this would increase performance by quite a bit, since only those emails that have a matching domain have to be checked against all contacts in the addressbook.

An example:
Suppose I would work at kde.org, i.e. I have a lot @kde.org addresses in my addressbook. So if 5% of my the spam-emails  I get use @kde.org, only those 5% have to be checked against all contacts with @kde.org in my addressbook. Those 95% with other domains, which do not have a domain that is part of my addressbook do not cause any query-traffic.

Another, quicker approach would be to include a checkbox in the wizard that asks the user whether to use the addressbook as whitelist or not.
