Hi all
Thank you for the various feedback I got.
I have re-worked my spamtrap SMTP dialogues.
But still I get weird behavior from yahoo servers. (not yahoo japan
this time, but servers like:
nm37.bullet.mail.ne1.yahoo.com
nm41-vm8.bullet.mail.ne1.yahoo.com
I see them repeatedly connecting,

You've invented a non-existent rule. I hope no one has made the

No. For one thing, Yahoo Japan is not the same company as Yahoo. There
is partial cross-ownership but they are operated separately.
For another, it's perfectly fine to send HELO if you're not planning
to ask for any optional features. These days

It's 2016. The mere fact it's sending HELO rather than EHLO is a pretty good
indication that it is either so decrepit or so deficient

Note to self, next time read RFC before sending email...
Old RFC 821 does not state, that a reply to HELO can be multiline.
After changing my spamtrap to only send one line in reply to HELO,
Hello
I see a lot of connections from servers with hostnames ending in:
bullet.mail.(skk|kks).yahoo.co.jp, but no emails sent.
So I sniffed one of the connections.
I see this SMTP Handshake:
Me=> 200 Welcome to my server
Yahoo <= HELO (hostname of yahoo server)
Me=> 200-Hello I do
