Were you sending mail to non-existent accounts or doing sender validation?



we weren't sending anything. We are an ISP providing email services to a
large number of users in  South Africa. Some of these users may have:

mis-remembered an email
mis-typed an email
sent to an acquaintance who had changed email provide (maybe because they
weren't receiving their emails :-)
responded to a forged spam
been abusing our system

but the possibilities cover a lot of ground. I have had a further
communication from netzero asking that I check for email addresses that look
unlikely. I am doing this, but apart from the fact that many of the large
ISPs provide emails that look unlikely due to the appending of digits, we
have over 10 official languages here and an address that looks unlikely in
English may make perfect sense in Zulu or Xhosa.

Subsequent communications have dealt only with the non-existent

resolved?

Yes, it does if most of the connections are for non-existent
accounts.  It can be resolved by not doing that.



As I said above we don't do that.

Thanks for showing the interest anyway
