that particular example is not the senders problem but the receivers

if one of your users is directing people to mail him via a forwarder that d=

then he must let you know to turn off spf checking for mail to him or mail =

or both when in tandem

or be told to simply stop directing mail from said forwarder via your syste=

as a sender cannot be expected to know that xxxx@yyy is a forwarder that do=
snt do SRS in front of a spf checking reciever
and should not modify their spf policy to deal with badly setup (by user) r=

if you allow users to use non SRS forwarders you should not reject spf fail=
