DKIM verification on itself is pretty useless, since it can only tell you which instance saw a mail and if the parts that are signed were altered since then. It only becomes somewhat useful when it's aligned with the From's domain-part and in combination with DMARC. I have a DKIM verifier here[0], but I am aware of a few bugs that still have to be ironed out before I want to make a release for it. But feel free to test it. I'm also looking into filter-spf, and hoping to work my way up to filter-dmarc. But I need to find proper room for that. martijn@ [0] https://src.imperialat.at/?action=summary&path=filter-dkimverify.git >> > > Sorry to hijack the thread but thanks for the great work on > filter-dkimsign :) I asked around but couldn't find a standalone / > minimal solution for DKIM verification on incoming mail without > rspamd.
