The 'Accept Messages From' Attribute is Blank in Advanced properties, Does Show in the Web Interface
The Accept Messages From attribute is blank in Advanced Properties, but Does Show in the Web Interface
This is because the Accept Messages From attribute is a constructed attribute consisting of the dlMemSubmitPerms and Accept Messages From attributes. Values for this constructed attribute set are stored in dlMemSubmitPerms.
Edit the dlMemSubmitPerms instead of the OnlyAccept Messages From attribute.
