I tested all of these with Linux running ECN, and Solaris 2.6 without ECN. When Solaris got connection, and ECN-Linux didn't, domain and its server got listed. Amazing share of these troubled destination systems run some firewall which thinks it is cool to fuck SMTP protocol. (I mean obscuring responses given by the remote system, frobbing incoming protocol if some particular detail doesn't please the rules it presumes to play with, etc..) I am contemplating to periodically turn off the ECN bit to let email out, but DaveM has veto there. This list is NOT exhaustive of domains with problems, it primarily lists only those who are subscribers of linux-kernel, and thus accumulated (al lot) more than 1 email with "connection timed out" status into vger's queue.
