Hello,
I changed the ssl ucc cert provider from godaddy to comodo and installed the new cert. All services are asigned to the new cert. Almost all emails on the receive connector work fine.
But the samsung printer and hrs.de seem to have problems negoatiating tls.
Patch level is CU11
checktls.com works with no errors.
Receive connector log shows this:
