The Daily Question-Problem all over again:

SMTP Security: Relay for addresses : enter your ip blocks

SMTP Security : Disable SMTP AUTH reporting : UNchecked

Border router: drop all (spoofed) packets on the outside interface from 
your ip block to your inside interface and to your ip blocks.

All client mail programs to use SMTP AUTH for sending mail to Imail.
