Depends on how many "spamware SMTP clients" -netblocks you have
to keep track of...
/now/ it's easy to find ebay's IP addresses, but they might
change, but fortunately not very often.

Anticipating future netblocks?
  http://www.cidr-report.org/cgi-bin/as-report?as=AS11643&view=4637
Checking for changes in SPF records?
"dnsmxip ebay.com" output [1]?
Triggering to receive (daily etc) test emails from these netblocks?

tcprules or other (cdb etc) feature for greetdelay?
=.ebay.com:allow,WHATEVERYOURGREETDELAYUSESTOWHITELIST=""

mailing postmaster@ebay.com and telling about relevant RFCs?

[1] yes I know, incoming != outgoing
