ISOC knows about this, but you actually need to contact ISOC's ISP.
But frankly it's a quixotic mission; SMTP mailers that break when they
find a non-ECN-tolerant SMTP peer are likely to encounter trouble for
some years to come.
The issue here is that there is a MAY in RFC 3168 that IMHO should
be a SHOULD. That's the first MAY in section 220.127.116.11. If your ECN
code implemented that MAY, you would not have seen a problem.

In its great wisdom, the IETF has divised a system to control congestion

routers out there which are "Explicit Congestion Notification" (ECN) broken:
One of this router leads to the ISOC web site. what is funny is to see the
above RFC is copyright ISOC. Could someone located in the Washington DC area
please contact the ISOC people and help them to be RFC compliant...
I have highlighted to ISOC the problem, they are aware, but understaffed and
this is a little bit tricky, but it should be a piece of cake for the IETF
