A combination of greylisting and RBLs have mostly solved this for me. Greylisting: when a new domain sends you mail, you initially reject it with a soft "I'm too busy right now" error. Real mail servers will queue it for redelivery. Spammers will move on. After some period of time -- 5 minutes? 15? -- you accept redeliveries, and you generally continue to accept messages from that domain without further delays. This is aggravating for many account signup procedures / lost password systems, but great in most other contexts. > Another suggestion: Don't offer e-mail addresses to others, or only to a > very few (spouse...) because doing tech support can be a lot of work.

Hardly anyone should be using self-signed certs for mail these days; Let's Encrypt is free and very reliable. -dsr- _______________________________________________ Discuss mailing list Discuss@lists.blu.org http://lists.blu.org/mailman/listinfo/discuss
