Hi,

Currently, I am using Dynamic Service from DYNU for my servers at home. My home is connected via fiber from Service Provider and has dynamic IP. I have setup my own email server at home and would like my email server is reachable from internet for sending and receiving emails.

Is there any service DYNU for this kind of service?

Thanks and regards,

Dedi

Does your ISP block inbound and outbound port 25? If so, you need email store/forward and SMTP relay.

You need to create an MX record in your external DNS pointing to your domain name, if your ISP is blocking port 25, then you need to use Dynu email services to forward those request to another port and create a rule in your router to forward those smtp request to your mail server on port 25.
