    I'm having an issue with GMail blocking my IP, even though I have a perfect reputation, am not on any blocklists, have a 10/10 rating on mail tester, and have submitted a ticket asking them to fix it.

    I've read on some forums the next suggested action is to "block them back"; the idea is that by making my server bounce their e-mails back, it will increase visibility to them, or to people using their e-mail servers and trying to contact me to raise a ticket on their side.

    How can I achieve this with Cloudron?

      That seems quite far fetched 🙂 I would be pleasantly surprised if they even reply to your ticket and accept to unblock. The big providers answers to no one in our experience.

      But back to the feature request, configuring bounce back message is not implemented. This is currently hardcoded.

      Currently, the template is from Haraka project:

      Received: (Haraka {pid} invoked for bounce); {date}
      Date: {date}
      From: MAILER-DAEMON@{me}
      To: {to}
      Auto-Submitted: auto-replied
      Subject: Message delivery failure notice
      Message-Id: {msgid}
      
      Hi. This is the Mailer program at {me}.
      
      I'm afraid I wasn't able to deliver your message
          "{subject}"
      to the following addresses.
      
      This is a permanent error; I've given up. Sorry it didn't work out.
      
      Intended Recipients: {recipients}
      Failure Reason: {reason}

        Can you tell me what triggers this to be sent? I tested blocking one of my own GMail addresses but didn't see this e-mail template bounced back to me.

        And I don't expect the bounce backs to cause my ticket to get attention 🙂 I expect people who want to work with me to see it, reach out to me through another channel, and then I'll let them know their IT needs to put in a ticket with Google if they want to receive e-mail from me.

          @djxx ha ha, sorry I misunderstood 🙂

          The bounce message is sent from Cloudron for undeliverable messages. You can send randomaddress@domain.com and you will get that bounce back message.

          Going back to your original problem, if gmail is blocking you , the only way to unblock is to wait it out. From your original mail, you are getting blocked at IP level. This means that gmail most likely blocked your entire VPS provider range. You have to set up a relay to get out of this situation - https://docs.cloudron.io/email/#relay-outbound-mails . If your mail is only getting to spam (instead of IP blocked), then usually you have to just "wait" it out. From many years ago, we just sent email from cloudron.io to various gmail friends and asked the to mark as not-spam. After that, it started going through. But gmail is a black box, who knows what they do now.
