I noticed I was getting a lot of spam from Finnish companies to firstname.lastname@. Presumably this comes from scraping the companies registry. Fastmail lets you block senders but not recipients from the GUI, so we have to nuke them from sieve instead:

### Reject firstname.lastname {{{
if anyof(
    address :matches :localpart "to" "firstname1.lastname1",
    address :matches :localpart "to" "firstname2.lastname2"
) {
    reject "haista vittu";
### }}}

Put it in the top box, i.e. above the spam filtering rules, so it ends up fully nuked and not in your spam folder.
