Spotted this on Usenet -- haven't seen this myself yet, but I've only
got a handful of netzero.net folks on my lists, all of whom (I believe)
are actively reading their mail.

> Newsgroups: lobby,announcements,news.admin.net-abuse.email
> Netzero has apparently implimented a brilliant policy of bouncing e-mail
> that sits in a netzero mailbox for more than six months.
> This caused severe problems this morning as mail from a list was all
> returned by netzero enmasse and severely overloaded the servers, exhausting the
> process tables with smartlist and procmail processes trying to remove the
> affected address from the dist.
> Problem is the address was already removed, but netzero just kept on
> sending messages back that were sent six months ago.
> I've recompiled the kernels to increase the size of the process table, but
> if this does not resolve the problem and netzero does stop this absurdity, it
> may be necessary to block all incoming e-mail from netzero in order to
> preserve the functionality of our mail servers.
