I have a problem sending mail from an external client to a file folder in Vibe.
The things I have tried are giving access to the folder for all users, guest and the groupwise program within the Vibe access control option.

Now the error is:
The error that the other server returned was:
554 message could not be placed ''_postingAgent' is not authorized to 'createEntries' modifications on this workspace'

Now what can I do to solve this issue? Is this rights I have to give within Vibe?
