I receive several dozen messages a day from
.ru domains (shown in the raw headers), that are always whitelisted by SpamSieve. I “Train As Spam” for each one – several hundred by now. I’ve uninstalled and reinstalled SpamSieve. Retrained it from scratch a couple times. Nothing catches these messages. This is merely an annoyance. These are messages that appear to be from me to me, on domains that I have hosted at Dreamhost.
(Small rant: Dreamhost email security sucks.)
