But there's nothing in the RFC about them relaying mail from: <>.
Mail sent from my account on the ISP to a bouncing address on my
machine bounces just fine; when mail sent from a third machine to
the bouncing account on my machine, the bounce from my machine is
rejected as an illegal relay by my ISP (the smarthost).
Since this is only an issue with relaying, and only servers will
generate mail from <>, anyone in the ISP's tech support department
capable of helping me will also see what I'm doing and refuse to. :/
