My domain is optonline.net, which is a major cable internet ISP. If you
block optonline.net then you stop email from millions of legitimate
addresses.

Why you replied by email, I don't know. However, as far as the blocked
domain goes, it's likely he has nothing to do with that.

Probably his ISP is using one of those obnoxious black-hole lists that
automatically detects spam and adds IP ranges from which the spam originated
to its database. Of course, since a third of all spam these days is being
sent from compromised but otherwise legitimate users, this sort of idiotic
solution results in innocent bystanders getting their email blocked.

My ISP provides this kind of "service", and once I found out what was going
on, I told them to disable it for my email. I don't get any more spam than
I used to, and I don't have friends and family complaining that they can't
send me email anymore.
