I should clarify my attitude to SPF/DKIM/DMARC I do check incoming mail SPF coz it's easy in both James and exim4, so why not, although checking incoming mail against online blacklists (DNSBL) pretty much solves the spam problem. I don't bother to check DKIM or DMARC. My experience is that you must implement SPF and DKIM for domains you are hosting as if you don't gmail, hotmail and other mega providers will put your outgoing mail in spam boxes without warning you - the logs will say queued for delivery / accepted. You may as well have DMARC as well although I can't see the point of it from a technical point of view. SPF and DMARC for your hosted domains is a DNS issue rather than an issue for james/exim4 or whatever. DKIM is a two part thing - you must have a public key in the domains' DNS and james/exim4 must sign outgoing mail with the corresponding private key. Fully dealt with at https://dmatthews.org/email_auth.html except that I've only done the DNS on a tinyDNS based system. I'd love to add info for BIND and I'll credit anyone who provides that in my writeup. -- David Matthews m...@dmatthews.org --------------------------------------------------------------------- To unsubscribe, e-mail: server-user-unsubscr...@james.apache.org For additional commands, e-mail: server-user-h...@james.apache.org
