# and submitter IDs.
#
# Entries are of the form:
#
#submitter-id:address-fragment
#
# where submitter-id is a valid submitter ID, and address-fragment
# is a full or partial e-mail address. Fragments are compared to the
# end of the "From:" header of a Problem Report in an attempt to
# identify the submitter based solely on email address.
# The string matched is merely user@host portion of the From: header,
# it does not contain any other text (such as <> or the full name
# portion of the address).
