Outgoing E-mail Error

Question

Hi,

There are so many mails waiting in mail queue and error queue even though I tried to flush or resend the mails. Our receive connector MessageRateLimit is unlimited but I still get this error. Do you have any suggestions to fix this problem?

Thank you

I would recommend trying to follow the steps in this KB: Outgoing Email Failed to be Sent due to 'Message submission rate for this client has exceeded the configured limit' Error

Our KB is actually linking to a helpful blog that explains better how to troubleshoot this, in https://exchangeserver20072010support.wordpress.com/2012/03/28/421-4-4-2-message-submission-rate-for-this-client-has-exceeded-the-configured-limit/

It is possible that your MessageRateLimit on exchange can be set to unlimited, but the instructions in that blog have you running the command

Get-ReceiveConnector -Identity "Client TEST-RS" | Set-ReceiveConnector -MessageRateLimit 20

where TEST-RS I believe is the name of the host machine Jira is running on.  And then checking your results with

Get-ReceiveConnector | ft Name, MessageRateLimit

So it does seem that Exchange can have set rate limits for each client set.

Are there any other parameters that I have to set?

You say "Our receive connector MessageRateLimit is unlimited".

I'm afraid you are misinformed.  It is limited.  The error message coming back from the mail server states that.  There's no other way to get that message.
