Re: More member-only anti-spam

[Emmanuel Duros <Emmanuel.Duros@UDcast.com>]

Lloyd,

My explanation was probably a bit too short but it is not only members
who can send mails to the udlr mailing list but also non members as long
as they reply to a confirmation message. Spamers don't reply to
confirmation messages, furtunately.

When I was at INRIA, I was administrating the UDLR mailing list, adding
and deleting emails manually from the list of members (it was taking me
more and more time...). Meanwhile, we started to receive spams like "how
to be a millionaire", "how to get a degree in computing" as well as
pointers to X sites...

Members were strongly complaining about these mails asking me to do
something efficient enough to stop this.

As a result, INRIA put in place a mechanism to add/delete members
automaticaly to/from the UDLR mailing list. It was also supposed to stop
spaming, and I believe it still works pretty well.

Today, when a non-member sends a mail to the mailing list, a
confirmation message is sent back to him. If the non-member replies to
it, the original mail is forwarded to the mailing list. Generally, if
the non-member is a spamer, he will never reply to the confirmation.

I believe that non-members can still send mails to the UDLR mailing
list, it just takes one extra-step. 
Would this cost be too high for an antispam measure ?

Anyway, if there is a standard way to administrate a mailing list, I
will be very glad to hear about it and see what I can do with INRIA.

Regards,
Emmanuel
