As far as I'm concerned (with a FAIL policy) they can, that's
the very idea of SPF's FAIL. Old 251-forwarding is broken by
design (since RfC 1123).
Bye, Frank
It's a nice theory, but if our experience here at Agilent is any
indication, we see over
1500/million messages to our (double opt-in) customer lists which are
forwarded in such
a broken manner (as indicated by macro expansion DNS queries).
Presumably the actual
number is significantly higher as the number of domains
checking/enforcing SPF records is
still limited.
Cheers,
Kurt
