Vladimir, Thanks for that article. You did cover all of the issues I've seen to date... including one I saw just this morning for the first time!
An organization's SPF has: v=spf1 mx include:smtproutes.com include:smtpout.com ~all include:spf.protection.outlook.com -all include:spf.emailsignatures365.com -all They couldn't understand why their outlook email was having trouble :) So, I've re-enabled spf for JUST my email server host, using JUST its ip4 address. Makes sense... sometimes it needs to send bounce-o-grams.
