I didn't think to test this until I saw this email but yeah after 
updating to 10.9 it no longer worked for me either.

My almost identical error was:
Oct 31 16:20:02 mailer sm-mta[88798]: STARTTLS=server, error: accept 
failed=-1, reason=unknown protocol, SSL_error=1, errno=0, retry=-1, 
relay=...

and I fixed it in my Mac 10.9 Mail by going to "Mail > Preferences..." 
and under "Accounts" then "Account Information" and selecting "Edit SMTP 
Server List.." and finally under "Advanced", I changed from "Use default 
ports (25, 465, 587)" to "Use custom port" with the value of "587".  I 
didn't change anything on the FreeBSD/Sendmail/SSL server side.

Oct 31 16:26:39 mailer sm-mta[95592]: STARTTLS=server, relay=xxxxxxxx 
[xxx.xxx.xxx.xxx], version=TLSv1/SSLv3, verify=NO, cipher=AES128-SHA,

Hope that helps,
