Submitted this because I send a lot of email (I run an email newsletter company) and have noticed a lot of people's forwarding setups are terrible and hitting deliverability due to our strict DMARC and SPF policies (and then they complain they didn't receive what they'd signed up for). We quite frequently get SPF errors reported back where people have things like Outlook or Hotmail accounts set up to forward to their other addresses and then their server complains Outlook or Hotmail's servers aren't in our SPF record. It's a total mess.
