I came into a struggle the last few days.
Using WAMP Server and following this Tutorial I set up a local email environment, and I wanted to make the emails reach accounts outside of the local host.
I heard you need to make some changes in the DNS zone, so here is my DNS Zone at Freenom.
Is is possible to make emails sent from a computer using hMailServer reach the outside world through a domain?
Thank you for your time.
It is possible but it depends on your Scenario.
If you are behind a Router or a NAT or a Dynamic IP-Address it's almost not possible to run a real World sending SMTP-Server and you shouldn't
If you have a Hosting plan (your own Windows V-Server or Root server) with Remote Desktop access and a static ip address it's and access to the DNS-Configuration of your Internet Domain, it is possible and recommended.
1) First you need to setup a DNS A Record which points to your static IP in DNS 2) You need to create DNS MX Record which points to your A Record
Now you can add a new hMailServer Domain and add accounts and sent Emails out. But you should setup a DNS A Record for IMAP or POP3 as well so you can Receive Emails and not only sending.
