PSA for folks forwarding personal email domains to Gmail

  • Jump to comment-1
    If you happen to have noticed that you aren't getting any email directly from me, or other people who set an SPF policy for their domain, the reason might be this: <redacted>: host[] said: 550-5.7.26 The MAIL FROM domain [] has an SPF record with a hard 550-5.7.26 fail policy (-all) but it fails to pass SPF checks with the ip: 550-5.7.26 [redacted]. To best protect our users from spam and phishing, 550-5.7.26 the message has been blocked. Please visit 550-5.7.26 for more 550-5.7.26 information. I've been seeing these bounces from a number of PG people for a couple of months now. The messages didn't use to be quite this explicit, but it seems absolutely clear now that <redacted>'s private email domain is trying to forward his email to a Gmail account, and it ain't working because the mail's envelope sender is still me. Gmail looks at my SPF record, notes that the mail is not coming from my IP address, and bounces it. Unfortunately it bounces it to me, who can't do anything about the misconfiguration. If you want to do this kind of forwarding, please fix your mail processing recipe so that the outgoing envelope sender is yourself, not the incoming sender. For extra credit, you could lobby Gmail to think a bit harder about who they send bounces to. From my perspective this behavior is not much better than a spam amplifier. regards, tom lane
