[GTALUG] lazy jail server admin forced to act

Mails from my domain have started to be rejected by gmail. To placate gmail, I've added an SPF record to my doman: mimosa.com. IN TXT "v=spf1 mx ~all" How to read this: v=spf1: this TXT record is an SPF version 1 record mx: email sent by mimosa.com should only come from its servers declared in MX DNS records ~all: any other mail from mimosa.com is bogus. (~ and - are slightly different.) That seemed pretty painless. I guess I should have done this a decade ago. I hope this works.
