Anyone out there know? Thanks. It was Netscape Navigator's internal mailbox retrieval utility, which was included in Mozilla Mail, too. You may need to "chmod 1777 /var/spool/mail" which is a slight security risk, since it allows your user account to create files in /var/spool/mail, such as the mailbox lock file. [There's also GNU MailUtils' external movemail utility.]
