A message memory (122) comprises an individual message portion (126) having an individual memory directory (127) and a maildrop message portion (128) having a maildrop memory directory (129). A processor (112) determines whether the decoded selective call message is an individual message or a maildrop message (204), determines whether a previously received maildrop message stored in the maildrop portion of the memory and having a maildrop address equivalent to the maildrop address of the decoded selective call message is "read" or "unread" (216), and provides identification information corresponding to the previously received one of the maildrop messages from the maildrop memory directory means to the individual memory directory means (222) if the previously received one of the maildrop me…
