Dear Microsoft,
I am reaching out via email to inquire about a specific matter. The reason for my inquiry is related to the need to send emails from our domain, which is currently required to have specific IP addresses registered with the mail server in order to use the Email API.
However, Azure Communication Service provides only an endpoint URL as a method for using the Email API. Even if we request this information from our internal IT department, it seems that we cannot gain approval without having a dedicated IP address.
Therefore, I would like to inquire whether it is possible to obtain a dedicated IP address that corresponds to the endpoint provided for the Email Service, as shown in the attached image.

Thank you for your assistance.
Sincerely,
Sungjae Cha
