Absolute newbie question about mx records

This is my first time trying to run my own website on my own PC. I have a dynamic IP address, so use DynDNS's nameservers to connect to the website. That's another story, but I'm getting there, slowly!

The problem I'm having is that I can't send or receive eMails to my domain mailboxes and I'm not sure what to add in the MX records, either within Sentora or DynDNS. I've tried, but nothing is received at all within the mailbox, but the address set up within the server config receives all eMails sent to the server.

I'm hoping, at some point, to host all of my own websites, and with some research it appears I'd be better off having a static IP address, but this is not possible at this time. Could that be the problem?

Dear angeljs,
I have the same problems, I have wondered the reason why I cannot send emails from Sentora or Zpanel for a long time. Nowadays I have discovered it.

First of all, most ISP blocks 25 smtp port. So ask your ISP if they block 25 port.

Then, most e-mail providers do SPF check,DKIM check, PTR check. If you don't have them, your server is blacklisted. they don't accept your e-mails.

Third, PTR reverse dns requires  fixed IP. Your ISP provides it. If you have dynamic ip, you cannot have reverse dns.

Finally, if you pass all the requirements, you have to set your windows firewall and router firewall to allow hmailserver ports 25/110/587 etc.

I advise you not to lose time with mx settings. use your own e-mail such as hotmail, gmail smtp at Sentora Configuration page. Be sure that you have allowed  windows firewall and router firewall settings for hmailserver ports (for both outgoing and incoming settings)
Thanks given by:
