   What would you do about a company/hospital system/university that has a
site license for their in-house email system -- kick all their subscribers
off your mailing list?  As our list is considered an academic forum more than
half of my >2000 subscribers get their list mailings at work through the
employer's email client.  It would be far easier for us to switch to another
list manager like Lyris or Majordomo than to have half our subscribers get
their employers to change clients.  Large Listserv lists are now a very
efficient way to spread viruses.  That has not gone unnoticed by the
virologists.
