I think the correct solution is that hallmark change its 'mail from' syntax:
MAIL FROM:<AT hallmark.domain:card-sender AT example1>
According to RFC2821, source routing SHOULD NOT be used my mailers.
Although MTAs MUST accept such a syntax, they SHOULD ignore the
routing and use only the last part.
This is why I recommend it: "modern" MTAs will skip the route part.
Hallmark does not want to receive bounces and SPF-aware hosts wants to
check the envelope sender. It is expressed exactly by the 'mail from'
example.
[ Additionaly it will be possible filtering out at the SMTP level
"e-card from a friend" messages if You dont like e-cards :-) ]
