A number of businesses will "legitimately" counterfeit mail from their
customers.
One example is Federal Express which may send email to the recipient of
a package
on "behalf of" and forged in the name of the customer sending the
package.
Other sorts of services routinely send out "invitations" or the like in
the name (and address) of the user.
Now I'm sure that most of us agree that that is a bad practice that
will have to come to an end. But has anyone had any luck contacting
such sites and persuading them to change their policies?
I have a client who regularly uses FedEx for shipping. While I can
certainly add
something like
?a:fedex-outgoing-servers/24
to my client's SPF record, I would prefer not to do so.
