hmm, that's a pain to keep up with, assuming you can enter all those
subnets inot Imail.
It means that anybody in the general public who gets logged to the
dial-up access server on one of those ip's can relay 1000's of msgs
without logging in to Imail since Imail trust those ip's for relaying.
This is really dangerous.
The best for everybody is to explain to your new users how to set up
Lookout, etc, for SMTP AUTH.

excellent observation and reaction! so, requiring SMTP AUTH is the
only way to go.
