If using email from JVPS servers, these are the MX records you need:
- A record for “mail.yourdomain.com” – pointing to your server IP.
- MX record for “yourdomain.com” – pointing to “mail.yourdomain.com”
- TXT record for your SPF – you can use this SPF generator. Example one is
v=spf1 +a +mx +ip4:18.104.22.168 ~all
