Hi all,

I can't get the mail store/forward working.

I've forwarded the correct port on my router. I've opened the correct port on my Zentyal firewall. Every time I test it I get the message that my server can't be contacted on that specific port. I've tried several different ports. I've tried setting up a Dynu MX server as my smarthost. I tried with and without credentials.

I just want to run my own email server but the instructions I found only cover a part of the setup.

The way I see it, you will have to make your mail server accessible from the internet first.
