Errors with port 25

We enforce security across all our tools, hence port 25 which is often the only option for self-hosted emails might have some issues with connection. If you are using major mail providers, port 587 is most likely available. Use this instead as it is more secured.

If port 25 is the only available option on your server, here is how to connect anyways:

  1. Go to

  2. Add using the older setup wizard to add your mailbox

If you need any help completing this step, we are always available on the chatbox on our website or you can send an email to
