Presumably you did that from a host that is not supposed to be allowed
to relay?

Set collapse_source_routes. In the next release of Exim, this is in fact
forced and you can't change it. I have made this change for three reasons
(a) the forthcoming RFC now says SHOULD instead of MAY and (b) people
don't know or understand source routing and (c) abusers keep messing
with it.
In 3.03 what happens depends on your configuration. Is bofh.de a local
domain? A relay_domain? It will do the relay checking on bofh.de. All
this is documented in section 40.4.

Rubbish. Tell him to go read the RFC. a@b@??? is
*syntactically* invalid. "a@??? is syntactically
valid, but means localpart=a@b domain=localdomain.example.com.
