Viktor, off topic perhaps but I am interested in your downer on DMARC. As I understand it, the point of DMARC is to prevent others from sending fake mails that purport to come from 'me' or 'my' domain. I am responsible for a few low-volume domains but this has happened to us, as it probably has to most others. The global email system surely needs a way to verify that emails are really from the purported sender and that they have not been altered on their way to their intended recipient, and DMARC (with DKIM, and not using p=none) offers this. Are there better alternatives?
