There are several anti-spam measures taken on the TWICS mail
system due to the high visibility of an ISP and the desires
of the customers.  TLUG is planning to move the main mailing list
from TWICS to the TLUG server this week or next week.  Alberto
and I will probably work on the transfer together.  After the
move, Alberto is going to be the main TLUG listmaster.   So,
in a few weeks, the mail policy on TWICS will not be an issue.

TLUG  members will be able to vote as a group on what if any
anti-spam measures we wish to take for the TLUG server.

Regards,
Craig
