Does anyone know the origin / usage for the form DPABPerson in Mail 8.x?
In the 8.x mail databases, documents are created (presumably) for type-ahead addressing using the form “DPABPerson” however this form does not exist in the design of the database.
the .ini setting only enables the preference “do not automatically add to the recent contacts” view. It does nothing to prevent existing “ghost” documents from interfering with email sends.
Just make sure you upgrade your personal address book (names.nsf on the client). Sometimes Notes forgets to do that, leaving its design at an older version.
When in doubt:
Get pernames.ntf from a clean, working client and replace the one in the data directory by that one.
Open names.nsf on the client (not the server) and do a Replace design with ‘Personal address book’ (pernames.ntf).
