ePADD is a software package developed by Stanford University's Special Collections & University Archives that supports archival processes around the appraisal, ingest, processing, discovery, and delivery of email archives.
ePADD maintains a list of words in a file named 'bannedStringsInPeopleNames.txt' which contains the words ‘undisclosed’ and 'recipient' in order to avoid 'Undisclosed recipients:' getting recognised as a person’s name. Maybe this doesn't prevent the name from appearing in the correspondent list because ‘Undisclosed recipients’ is used as email address in ePADD for which 'bannedStringsInPeopleNames.txt' is not used?
Sometimes Mbox emails contain:
To: "Undisclosed recipients:"
