I want to understand the points below:

1- to enable public users out on the internet to send email to my organization, I should register MX and A record  with the ISP. Correct?

 how do they show at the registar?
A : MyCompany.com  64.64.64.64
MX : Mycompany.com
Correct?

2- once the A and MX records registered, public users can send email to Mycompany.com , and it will come to my public router interface 64.64.64.64 , and from there how does it finds the route to my exchange server Mailbox??

3- if a public user , send email from Yahoo.com to Mycompany.com, I wonder if it goes through CAS server, or just from Hub server to Mailbox server?

Thanks

2- it sounds like an Access List should be configured on  the router. If so, can you paste the config here?

3- If I understand your point, is if the emal is coming from Yahoo.com. or Hotmail.com, Gmail.com, then it will go to the HUB server role then to the Mailbox server role, it doesn't go through CAS server role. Correct?

1- OK on the public DNS  at the registrar for instance GoDaddy.com are the records gonna show as follows ??
Host record (A) = company.com  64.64.64.64
MX record=  mail.company.com

2- at the router or firewall level, can you please paste the NAT commands. ?
and the NAT will point to which IP address?

Host record (A) = company.com  64.64.64.64
Host record (A) = mail.company.com  64.64.64.64
MX record=  mail.company.com
