Hello, I need to block a Hub Transport Server from being able to send e-mails to the internet. Someone told me to suspend all it's message queues. This will not block all new messages even internally and will not the message queue always build up since it will be suspended ? Thanks

If you only have one send connector for the internet, it is easy enough to disable: Set-SendConnector -Identity "Send Connector" -Enabled $false If you have many and you want to disable them all: Get-SendConnector | Set-SendConnector -Enabled $false JoeJoseph M.

If you suspend Queues messages will be there in Queue and nothing will happen to them. They will get stuck in Queue. However if you want to stop transport server to send mail to internet, following option you can try:- 1. what Joseph told you to disable Send connector. 2. configure a transport rule for all messages from inetrnally to externally - and take whatever action you want (silently drop, delect or fwd somewhere else etc.) 3. Do not provide internet connectivity to transport server.Best Rgds, Ashish | Unified Comunication | MCTS | MCITP | Please remember to select option "Propose As Answer" if solution work for you | My posts hold no assurances, no promises, and they measured no rights.

yes but If I disable the Send Connector, will internal e-mails still work as normal ?

There will be no impact for internal users.Best Rgds, Ashish | Unified Comunication | MCTS | MCITP | Please remember to select option "Propose As Answer" if solution work for you | My posts hold no assurances, no promises, and they measured no rights.

“Suspend queue: This action temporarily prevents delivery of messages that are currently in the queue. The queue continues to accept new messages, but no messages leave the queue” ---------Refer to <Managing Queues>Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Yes, what I did not understand is how internal messages continue to work if the queue is halted
