When a subscriber's address changes after they have subscribed to the
list I manage, I generally notify the affected user I will delete their
subscription under the bad address and ask them to re-subscribe under the
new address.
 
Recently Genie.geis.com renamed itself to genie.com and I did this to all
affected subscribers to my lift, which were exactly two people.
 
My reason for not issuing a delete and subscribe for the user myself is
simple.  If the user still wants to receive the list, they will
re-subscribe.  If they are not interested in receiving the list, they
will not re-subscribe but the ultimate decision is up to the subscriber.
 
Now if the user is on a system where their address changes each session
they are logged on, you have a serious problem.
 
My list used to be send: public but I got tired of spam and send:private
has virtually eliminated spam from my list.
 
Good luck.
