exim sending email and bouncing it

[mikesouth]

Ok I cant figure this out

i email to one of my valid emails and domain

the email gets delivered and forwarded properly

but I get an error back to my sending address that says it failed as an unroutable address

so in other words it works but it emails (the sender) back telling me it didnt

any idea whats going on?

can you post the full error message here? i.e. the error code, etc.

Relevant entries from your Exim logs would be good as well.
