Hello

My DC has DNS activated, properly setup, up and running in our LAN. Connecting to our domain from local netwrok is instaneous

I am not very much very much skilled for the following

our mail server name myserver.mydomain.com is managed by our ISP.

What and where in our DC/DNS should I add an entry so that myserver.mydomain.com is forwarded to the Local IP of our mail sever.

Without this the local email clients are trying to connect to our mail serer trough our Public IP

Thank you very much

You should create at Your local DNS server new DNS zone "mydomain.com" and then within that zone create MX record that point to A record "myserver.mydomain.com" IP address(both types of DNS records you can create by Microsoft Management Console with is ordinary used to managing DNS). After that your LAN clients will be able to resolve IP address of your local mail Server(MX record). This is accurate for scenario with SMTP server however if your email server is POP3 or MAPI you Just need to create A records for this server. I hope that your local email infrastructure is already setup for chosen scenario.

if your ISP maintained dns entry is myserver.mydomain.com, what is your local domain? Is it mydomain.com or something different? Is your internal domain and your external domain (this is the dns entry that your ISP maintains for you so that your servers are contactable for emails via internet) the same?

If this is the case, then you dont need to create a MX entry in your local domain. Since your local domain is already mydomain.com, create an A record in your dns. this entry will be myserver.mydomain.com and the ip address attached to it will be the ip for your local email server.

It's sounds that your problem had started after DNS modifications? If Yes that you should add DNS record for your www web server("A" type) in your DNS infrastructure(with is used by your PC's). You should keep in mind that such scenario isn't optimal from operational point of view(you should be informed by your IPS about every changes of your web server IP, if any).
