MDaemon 11 and TLS 1.2 - 04:41am Nov 14, 2020 CDT - Thank you!

To help someone else google and find out this problem:

<-- 220 2.0.0 Ready to start TLS

SSL negotiation failed, error code 0x80090302

<-- 220 2.0.0 Ready to start TLS

SSL negotiation failed, error code 0x80090308

MDaemon 11 and TLS 1.2 - 04:48am Nov 14, 2020 CDT - I have MDaemon 11.0.4 running at Windows Server 2008 R2 SP1.
KB3140245 installed. TLS 1.2 activated in a registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

But MDaemon uses only TLS 1.0 not 1.2...

OK
