good afternoon.

I'm using your send receive relay system as my port 25 is blocked and all is well server side its getting the emails but not sending them.

When i try to connect a client to my hmailserver its telling me that the incoming mail server (mx1.dynu.com) that the username or password is wrong but nowhere in the guide does it mention about needing a username or password or what they might be.

If anyone could help me resolve these issues i will be most grateful.

If you want to use the SMTP outbound relay service, the relay server is relay.dynu.com not mx1.
