You don't say whether they are all at the same host or not so it's
difficult to say.  If they are all at the same host, or even the same
subdomain.domain , 99.9% of the time it's a local screw-up (the same can
happen with "user unknown").  If you've several subscribers at one place,
and they could be on different hosts, and suddenly they all get
autodeleted, the problem is usually at their site.
 
About all you can do is say "sorry, please resubscribe, the problem is
probably on your end, please consult your local people about it" and let
the postmaster at that site know there is a problem. Usually, in my
experience, these problems are transient and by the time the people try to
resubscribe the problem is cleared up.
 
And keep in mind that some places love to make life difficult by playing
musical hosts, though that usually doesn't cause mail to bounce, but
causes your subscribers there to lose control of their subscriptions.
We've subscibers whose addresses have changed at least three times in one
year.
