[Serusers] "Relay not allowed" error number?

[Federico Giannici]

What is the correct error code number for the error "Relay not allowed", 
that is a request that isn't either FROM neither TO an user of ours?

I'm undecided between "403 Forbidden" and "502 Bad Gateway".

What do you think?


Thanks.
