Please note that of course, I can only speak for myself and the
system I am responsible for. I really don't know if netzero.com
uses a similar system or not. I have no idea what basis their
blocking has, nor do I know whether it's in any way sensible or not.
Granted, but it seems to me that it is very much easier to detect these
violations at the destination that at the source. The implication is
that we
must keep count of every failed recipient for every sender on our domain
If mail from your network is sent through your SMTP server that
info should be in your logs.
If not, you might have to ask the admins of the system that
blocked you for info about it.
If you had been blocked here and asked us for the reason, I would
check the database to see what kind of behaviour resulted in the
block, and wether the block was still in place. Our temporary
blocks based on these kind of things has a time window of a few
minutes, so once you asked us the block would most probably be
gone allready. And they don't tend to actually stop mail sent
from retrying mail servers to legitimate users.
