Sorry for the late reply.
Thank you very much for the instructions with examples. I do appreciate
it very much.
I have done the setting in postfix. Will report back on the result.
You should also reach out to the merck.com postmaster and try to resolve
the underlying issue. Why is their MTA closing the connection in the
middle of STARTTLS?
Will do that. I hope the sysadmin there will be responsive.
Once again thank you for the help.
P.V.Anthony
