1) The entries in 'o_addr' and 'use_akas' are indexes into
the list of AKAs in IMAIL.CF, minus 1. eg:
im_config.aka[o_addr-1]
A value of 0 means 'no address'
2) the 'user_bits' entry allows third-part software to store
extra information in IMAIL.AR. Their meaning is program-
specific, so be careful when making use of them!
3) IMAIL.AR knows three predefined areatags:
BADMAIL for the IMAIL badmail area,
DUPES for the IMAIL dupe area and
PERSMAIL for the IMAIL personal mail area.
All three boards are treated as local areas and
the BADMAIL area must be present and non-passthru
otherwise IMAIL will not run.
