POP and sendmail mods for no system accounts

[Barry W Anderson <bwa @ shadow . dbapic . com . au>]

Along mail lines, does anyone recall seeing posted or mailed
(reasonably) recently the mods to popper and sendmail to allow users not
to have system accounts? Have searched Alta Vista till weird hours of
the morning without success and am now at the stage where unless someone
else can jog my memory as to the location, I'll write the mods myself -
and I HATE reinventing the wheel.

cheers,
