I am working on SharePoint server 2013, and i have added an Announcement list. then i configure the announcement list to receive in-coming emails,so currently our domain users can send an email to the following address
ListA@OurSharePointServerName.com and a new item will get created inside the list.
But of course if external users try to send an email to
ListA@OurSharePointServerName.com it will not reach the list , at-least since
OurSharePointServerName.com is not available to public users .. So is there a way to force this to work , so external users can send emails which will get populated inside our SharePoint list ?
