From the mail log, it looks like messages like

(in reply to MAIL FROM command))

is the problem - mx.develooper.com needs to be able to resolve the machine name specified in your FROM header. I'm not that familiar with Macintosh, but is your host name specified as Macintosh.local? If so, if you have a permanent IP address, try changing your host name to that associated with the address.
