This idea has been merged into another idea. To comment or vote on this idea, please visit POLITEMAIL-I-68 Disable auto replies for all email sent to a large mail list..
For larger organizations and distribution lists, it's important to suppress auto-replies (unless you want to be flooded with hundreds of out of office messages -- eek). That said, it's difficult to always remember with every single communication to select this feature every time. It would be great to have the option to set it as the default, or have the inverse option instead (i.e. "include auto-replies") for those occasions when we actively are looking for that information.
Thank you for your idea. We will share this with the Development Team.
