You opened the thread describing it as a "personal mail server". I interpret that as being a mta serving just you, or a few select family members/friends. As such you can (should?) be highly selective. If you only use ISP A, why should you allow from any other source? It's not as if you won't notice when you change providers. If John uses only provider B, why would you let a login from ISP C? This is not about limiting people. It would be wrong not to let someone access a public place¹ based on their race or nationality.² We are talking about your own server, such as your home. It would be perfectly fine not to let any Elbonians to the door of your house if you don't have any Elbonian friend (or you know they will tell you before paying you a visit) or, conversely, to ask the doorman to filter out any visitors not wearing hats. Of course, they would still need a key to open the door to your house, but there's no reason to to a quick filtering before letting them try their lock-picking skills. Regards ¹ In a broad meaning, including privately-owned ones, such as a shopping center. ² Ok, you may argue that an embassy might be considered a "public place" and yet to have a legitimate reason for being highly selective on your nationalitiy.
