Have followed all required steps outlined in pmta user guide for using the

Never mind you can close, turns out i had set pmta to dummy connections from 
all local ip's on port 25 with the directives:
dummy-smtp-port 25
in the pmta config.

Commenting out or setting to port 0 disables blackholing these connections.
Now everything is working correctly.

Thanks
