Does anyone have a complete list of any other from addresses/formats that
will cause load issues on Domino. I know from Ian's bugtraq post that
anything@[127.0.0.1] will do it. What about anything@localhost,
anything@[servers-IP], etc.? Has Lotus fixed this in any Domino release,
or are they all brain damaged.

Just like when MAPS surprised everyone with no more free service.
