About p25.dev
What is p25.dev?
p25.dev is a subscription based service that gives you inbound (MX backup) and outbound (relay) email infrastructure for your self-hosted email server. We monitor your email servers and your DNS configuration and alert you if delivery or reception of emails could be disrupted.
For the MX backup, you can receive as many emails as you like. Sending has a generous allowance based on your subscription tier.
The choice of MTA is yours. We provide instructions for mox and Stalwart because both options are complete in terms of modern emailing. You could also use software such as Postfix if you are willing to invest more time for a complete setup.
