[C38] spam on the C38 listserve?

[Charles]

When I set up the Catalina38 listserve after Sailnet tanked, I developed 
a process to ensure we would not be spoofed or spammed.  Some things it 
might help to know:

1. Each new member of the listserve has to be specifically allowed to 
send messages.  Phil Gay now does this.
2. There are also limits to large emails and to the number of emails one 
member can send within 24 hours.
3. There are no restrictions regarding receipt of messages.

So, if someone wanted to "take over" our listserve, they would have to 
hack the master password in 5 tries (it locks you out if you try more 
than that).  The server we sit on is one of the most protected 
commercial servers in the industry (I chose them for their security 
reputation).

That leaves the possibility that someone could hack one of our member's 
computers and try to send that way, but they would be locked out after 
just a few messages.

My best guess is that someone has hacked the Sailnet listserve and those 
of you who subscribe to it are getting these messages (I have not 
received one for the same reason Phil gave).  Given their volume, they 
probably have not set in place the same manual procedures we have and 
are therefore vulnerable.

By the way, DO NOT respond to the Unsubscribe message!  By doing so, you 
are probably giving the hackers an invitation to visit!
