Everything is working except relaying
I get timeout errors such as:

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?
