    So if your instance is https://iusearchlinux.fyi then here is what I would do. For most of this it can be done in the DNS section of the place you registered the domain with.

    NOTE: It looks like you are using Google Domains. Those are going away. So you may need to move to a differe registrar: https://9to5google.com/2023/06/15/google-domains-squarespace/

    1. SPF record. This is a txt record (text) record saying “these servers can relay from this location” For you the content should be

    v=spf1 ip4:45.33.23.198 ~all

    1. DMARC record. is another text record that says “Do this if SPF or DKIM dont match.” If you put it in strict mode, you need BOTH SPF and DKIM. DKIM is a bit of a pain (though is much better). But if you start with SPF and the default relaxed mode you are probably fine. The record here would be for the _dmarc subdomain as well ie: _dmarc.iusearchlinux.fyi. In the below case I am saying “reject emails that are trying to spoof my domain” you can set it to quarantine but there is little need here.

    _dmarc.iusearchlinux.fyi 900 IN TXT "v=DMARC1;p=reject"

    1. PTR record. You are using digital ocean. These are good to setup because many email servers will look up your IP and make sure it matches the domain. It shows you own it. Dont know how to do it in digital ocean but on linode its in the networking section of the UI. Because linode/DO owns the IP they need to make the change for you as opposed to all the previous steps being done in your domain registrars portal (ie: goodle domains)

    This will get you most of the way to ensure Digital Ocean doesnt get pissed and suspend you for spamming or the like. They may also restrict port 25 outbound due to abuse. For linode you ahve to log a ticket if your account is too young. Your other alternative would be to use a relay host, like sendgrid. Its possible to relay through other services like gmail, but it would probably get your account flagged for something like this. So I would stick to sendgrid or some other relay provider if DO support wont allow you to relay off your droplet.

    The default postfix setup is a direct relay, which DigitalOcean may block. So you can setup relay with these instructions: https://github.com/wader/postfix-relay#relay-client-authentication This is the docker container bundled in the lemmy-ansible app.

      I added the missing records. Lets hope its working soon. I will have to wait to move the domain since it’s less than 60 days since i bought it.

        Best of luck. If you have any questions feel free to holler.

        I’m not a lemmy (or docker) pro, but I have done a few postfix and email setups including a lot of email admin, dmarc/dkim/spf etc.

        It does look like digital ocean may be blocking the normal mail ports outbound. So you’ll want to make sure you can work around that or get them to open it.

          I wrote them about opening the port but maybe it will already be open since my acount is older. Thank you again!
