A:

If you use your ISPs mail server as a relay server, then your IP doesn't really matter since your ISPs mail server will handle the external communication.

 

If you wish to download emails from your ISP to your local server, you could use something like fetchmail.

    Hi,

     

    you shouldn't. Most large ISPs and mail service providers will blacklist your server if it sends from a dynamic IP.

     

    HTH,
