Apparently for outgoing mail these are both complete in the cPanel Exim build. Incoming mail verification lacks the functionality still.
Is there any beta incoming functionality in EDGE or CURRENT yet? Do we have any ETA for being able to use either or both fully?
The need becomes greater as places like Yahoo impose them on us by screwing up our users' email due to our inability to comply!
Related to SPF there remains the outstanding matter of an SRS (rewriting) option, to allow continued use of forwarders to work. Loss of forwarders would be disastrous for us.
