I noticed on the webhostingtalk.com thread that you offer email forwarding
for domains hosted with domaindns - do you support SRS (Sender Rewriting
Scheme) on emails you forward?
Without doing srs it's possible for domains that publish spf records that
end in -all to have emails falsely rejected, if they send an email to
someone who has their email forwarded to a destination that does strict spf
checking.
It is possible for screwed up mail receivers to falsely reject email
for all kinds of reasons. SRS is just one tool that a mail receiver might
use to manage their forwarders. It is not required. All that is
required is to know who their forwarders are. If they don't know,
then they can't (correctly) do strict spf checking.
What is much more important that SRS in a forwarder for someone checking SPF
is that the forwarder also checks SPF. It also helps if the forwarder
publishes SPF so that the recipient doesn't have to manually track
the IP addresses of their forwarder.
