Hi,
I have my registered domain somedomain.com which is also registered thru your DDNS service. I have hosting on my own server. What I need is to establish (among other things) a mail server. I already installed MailEnable mail server and configured it. I can receive emails thru this server but I can not send emails due to the fact that my domain is not accepted as being a relay, probably because of the dynamic IP address or similar issues. What I read is that ISP should help with this issue, registering by themselves my domain as reliable, but my ISP is not offering such kind of service to individuals, just for companies with a leased line. Can you please help me, i.e., is there a service you can give me to register my domain as a reliable domain for accepting emails by other domains?

Kind regards
Nikolce Petkoski

You can use the SMTP outbound relay at https://www.dynu.com/en-US/Email/Outbound-SMTP-Relay to relay emails through a third party such as Dynu.
