Dear All,
I have an Exchange Server running in my organization and is successfully serving to internal users. By using one of the POP3 tool i am successfully receiving external user emails to Exchange Server as well. But i have few confusions and problems
1. I have oracle based payslip system that is unable to send payslip to those who have their emails on yahoo and hotmail but it successfully sends to all who are confiigured with exchange server. How to resolve this???
2. Second issue is why we need to use POP3 external tools to setup with Exchange in order to handly pop3 mails.?? why exchange do not have such functionality???
3. Lastly, I have implemented One Exchange Server along with its DAG as high availability. for external users we have configured our ms record entries to the domain hosting company and whenever they have issue in their firewall they block exchange public ip addresses and our external email are then blocked. What is the recommended Exchange Scenario in this regards???
Thanks
Regards
