halo,
as title, I wondering how to limit a sender or IP to be able to send 20 emails in 10 minutes only?
the limited should effect on outside sender only , the internal user should not be limited.
thanks :)

Sorry, no such specific setting in Exchange itself. You may want to look at your anti-spam solution on a SMTP gateway to see if that capability exists.
You can look at the message throttling options here:
BTW, I know Set-ReceiveConnector has properties : MessageRateLimit and MessageRateSource
but, the message limited by per minute which is not achieve my requirement. I want to the time slot can be settable. e.g. 10 minutes or 1 hour.
thanks for the reply.
I wondering in Set-ReceiveConnector -MessageRateLimit , how to count the message?
e.g. one external client send an email to my company with 5 recipients and cc to 10 recipients.
show to count the message in this case, 1 message? 5 message ? 15 message ?
thanks!
BTW, we using symantec message gateway and they said this should do on exchange side. :) interesting hahaha
The time slot is not settable in Exchange, you should look for third-party tools or scripting something.

does anyone know the messages definition ? by message id or by what ?
Message limit would be per message from the same IP for messages from the internet. Each message should have a unique message ID, but thats not how its governed.
From that doc I linked:
IPAddress on the following default Receive connectors:
• Default <ServerName> in the Transport service on Mailbox servers.
• Default Frontend <ServerName> in the Front End Transport service on Mailbox servers.
• Outbound Proxy Frontend <ServerName> in the Front End Transport service on Mailbox servers.
• Default internal Receive connector <ServerName> on Edge Transport servers.
