Running your own personal, non-commercial server may be just fine. But if you’re business is pumping out volumes of email, no amount of DMARC, DKIM, SPF, CFL participation and fighting to stay off IP blacklists will prevent you from eventually succumbing to the user that clicks the Junk button to delete their emails. This will tank your domain’s reputation and get your emails routed to Junk (or silently discarded) for all recipients at the big ESPs like Gmail, etc. SPAM scoring is outsourced to companies like Symantec, CloudMark and others. They are the mail-zapping, score-keeping monoculture of the email ecosphere. You basically need a large company who will take your word for it that you’re not SPAMming and interface with the filtering industry on your behalf to de-nerf your domain once the Junkie McJunkbuttons of the Internet screw your reputation over.
- sedachv 9y agoWhat is CFL participation?
- CodeWriter23 9y agoCustomer Feedback Loop. When Junkie taps the Junk button you get notified by the ESP to delete them any mailing lists and never email that address again. They typically track this as a metric against your domain. And some ESPs, like Comcast won’t even sign you up to participate unless you’re big.
- danieltillett 9y agoYep. Basically the big email companies have outsourced their anti-spam filtering problem to the email service companies. I used to run my own email server for around 15 years with minimal issues, but I gave up when my mail started disappearing into the hotmail/gmail/yahoo blackhole.
