batch unsubs and subs

[Hand, Brian C.]

if a have a large list say 325000+ address to add or delete to a mailing
list and have them in a text file.  one address per line.  can ezmlm-unsub
or sub be made to patch them all at once.  Right now I am doing a for loop
and calling ezmlm-sub or ezmlm-unsub for each line.  Right now with the
amount of addresses it is taking roughly 4 hours to complete.  Is there a
way to speed this up?

Thanks
Brian
