Thanks for your excellent answers, Steve and Mark.
Mark, I might pass your generous offer to work with cPanel, on to the webhost
(again), to be passed on to cPanel, once I've heard back from the webhost re
the timing of when sender_verify was turned on (presumably through a cPanel
update). When I asked the webhost yesterday how long it's been turned on, the
response was:
'Actually, the "Sender Verify" option is the default and recommended by
cPanel, so I don't think it was touched by our support staff. I'm attaching the
screenshot of this setting for your convenience.'
I won't attach the screen shot, but it describes the "Sender Verification"
option as "Verify that the domain mail reports as it origin actually exists".
(The grammar looks strange to my uneducated eyes - maybe that should read
"Verify that the domain origin email address actually exists" or "Verify that
the domain origin actually exists".) The options are "On (default)" and "Off".
"On" is selected.
Jim, I don't know the answer to your question, but thanks for commenting.
Terry
