Open a support ticket asking for outbound SMTP +to be unblocked, and say what the host is for. + +If the answer is no, LambdaMail can still send through a relay: set `RELAY_HOST` +and friends, and the relay is added to the published SPF record automatically. +Receiving is unaffected either way. + +### 2. Reverse DNS (PTR) + +The PTR for your public IPv4 must resolve to `PRIMARY_MAIL_HOST`, and that name +must resolve back to the same address. This is called FCrDNS, and Gmail and +Outlook will refuse or spam-folder mail without it. + +**The PTR is set by whoever owns the IP block — your VPS provider, not +Cloudflare.** It is usually a field in the server's control panel. + +```bash +dig -x 203.0.113.10 +short # must print mail.example.com. +dig mail.example.com +short # must print 203.0.113.10 +``` + +### 3.

Sign in to the webmail at `https:///user/login`. +2. Go to **Settings** and enrol a second factor. The admin console requires + one and will refuse to open until it exists. +3.

Watch it: + +```bash +docker compose logs -f protocols | grep "DNS reconcile" +``` + +It is idempotent, and it never deletes records it did not create — anything +unexpected is reported as a conflict rather than overwritten. + +Without a token, add the records by hand.
