NDR for non-existent domain (5.4.4)

By default, NDR (5.4.4) of an email sent to a user with non-existent domain is sent to postmaster's mailbox. If you want your users to get NDR when they send email to a wrong email address (domain in this case), you need to remove 5.4.4 code from Transport Configuration.

In Exchange 2010:


go to Organization > Hub transport > Global settings > Transport settingsremove code 5.4.4 from the list

In Exchange 2013/16
Get-transportConfig to check settingsFind GenerateCopyOfDSNFor and the codes (if 5.4.4 is on the list)Example: {5.4.8, 5.4.4, 5.4.6, 5.2.4, 5.2.0, 5.1.4}Copy ALL codes (from bracket to bracket)Paste into NotepadRemove 5.4.4 from the list (remove 5.4.4, )Set-transportConfig -GenerateCopyOfDSNFor "5.4.8, 5.4.6, 5.2.4, 5.2.0, 5.1.4" Users will get NDR immediately.

Install Docker on Microsoft Windows 2016

Microsoft Windows 2016 supports Docker engine, running containers natively on Windows. To install Docker on Windows server you need to run:

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -ForceInstall-Module -Name DockerMsftProvider -ForceInstall-Package -Name docker -ProviderName DockerMsftProvider -ForceRestart-Computer -Force After that run:
# Open firewall port 2375
netsh advfirewall firewall add rule name="docker engine" dir=in action=allow protocol=TCP localport=2375# Configure Docker daemon to listen on both pipe and TCP (replaces docker --register-service invocation above)
Stop-Service dockerdockerd --unregister-servicedockerd -H npipe:// -H 0.0.0.0:2375 --register-serviceStart-Service docker
