We have a puzzle. mpd-net is one of the cancer  support lists hosted at 
listserv.acor.org   For the past several  weeks,  we have been receiving  
approximately 5 requests a day to  subscribe to our listowners' mailbox  from

[log in to unmask],

mpdinfo.org is the domain of  the CMPD Education Foundation and our website 
for myeloproliferative disorders  is at www.mpdinfo.org

I looked up megawebservers.com and that site is  supposedly an antispamming 
organization.  I reported this to  [log in to unmask] but just got a 
canned response.

I've asked the  ACOR postmaster if there is any way to block this spam from 
reaching us.   No response.  Is there anything we can do to stop this?   So far 
 this entity has only repeatedly sent "subscribe mpd-net"  (no name).   Any 
suggestions?
