Hi,
after upgrading to MR-9 from a fresh install of MR-8 and restore I have had to disable mail scanning because the XG causes the Apple devices to not verify the various mail servers even after the installation of the CAs.
One server reports the certificate fails to meet pinning requirements and I suspect that there are too many older CAs in the keychains which need to be deleted. But the iPad and iPhone did not have any profiles installed. One other server returns incorrect userid or password which quite happily work when mail scanning is disabled or on the outside network.
HTTPS scanning works for web sites, I am a little unsure to the exact cause of mail insecurity.
