Hello,
I am using the same set up as above, with a smiler issue, however I have already checked my dns settings and everything there is correct.
The error from round-cube is:
SMTP Error: [450] 4.7.1 <END-OF-MESSAGE>: End-of-data rejected: Access denied
The log is below: (edited address's in log to prevent spam)

I am sure I am missing something simple, but am unsure what, any suggestions would be very helpful.
Thanks
