I understand that lacking reverse DNS can cause these problems, but I have corrected that problem and now pass FcRDNS test. But these problems continue. All other mail works fine.
The only other possibility I have encountered is to change a timeout for sendmail. in sendmail.cf
Any suggestions?

RE: Can't get sendmail to relay

Just telnet port 25 to those relays to see if they work.  The paypal one was slow, but bennettconstruction one seems fine and the .cn one did not respond.  I don't believe you are getting far enough for the reverse DNS to be in play!

$ telnet smtp.secureserver.net 25
