                                I am hosting my own email server. It can receive mail on port 25, but unfortunately my ISP blocks sending on that port.  so I chose  your "SMTP Outbound Relay" service,  which I use on port 26. it works, but then I can no longer send mail. How can I resolve this issue? Should I change my service from Dynu or is it a configuration issue?

                                If its like my ISP, they block port 25 is both directions, except to their SMTP server.On my mail server I have a "Smart Host / Outbound Mail Gateway" configured that point to the ISP's mail server and it relays all my email. It does require a login, but is transparent to your domain email addresses.Basically you have to SMTP relay in (Dynu) and SMTP relay out (Your ISP SMTP server).
