Indicates whether all e-mail that is addressed to an e-mail distribution group or only authenticated e-mail is received by the group from Microsoft Exchange.
public enum DistributionGroupFlags
|None||All e-mail is received by the group.|
|OnlyAllowAuthenticatedEmail||Only authenticated e-mail is received by the group.|
The DistributionGroupFlags enumeration is used primarily as a parameter for the CreateDistributionGroup and ModifyDistributionGroup methods.
If OnlyAllowAuthenticatedEmail is passed, Microsoft Exchange deletes unauthenticated e-mail addressed to the group.
