Also add DMARC to the list aswell, and make sure to warm up the domain again once you're done.

  What does "warm up" mean in this case? Send a few emails? Also, what policy do you recommend fro DMARC: none, quarantine, or reject?

    This is what mailgun recommends for warming up email / email reputation. https://www.mailgun.com/blog/domain-warmup-reputation-stretch-before-you-send/ https://www.mailgun.com/blog/domain-warmup-reputation-stretc... If you're just starting out, start with none. Quarantine or reject needs to be carefully monitored over time.

    DMARC: Set is as p=none and read your reports from the RUA tags. Once you are confident that all the legitimate mail is aligned, then go straight to p=reject. Many will recommend quarantine, but it's better to have an email bounce back immediately vs silently get lost in a spam folder. Outside of troubleshooting there isn't much use for P=Quarantine in DMARC or '~all' in SPF.

      ~all in SPF is a different beast, since -all breaks forwards. There's still an unreasonably large amount of people heavily reliant on forwards, so I'd not go as far as to recommend ~all to people who are not 100% certain of the consequences.
