421 4.4.2 Message submission rate for this client has exceeded the configured limit

On of my Outlook 2007 user is getting the following error.

Problem:

'Cannot send the message.Verify the e-mail address in your account properties. The server responded: 421 4.4.2 Message submission rate for this client has exceeded the configured limit'





Findings:

As per my observation user is not getting this error freequently, but he is receiving this error when is going to send bulk mails at a time(every evening before leave the office perimeter this user compose lot of mails and send all the mails in one shot time).

I verified the same @ exchange server Receive Connector level using the powershell command and find out that one of our Receive Connector had limitation of 5 message rate limit(if any user is going to send more than 5 mails concurrently then he will receive the above error).

Get-ReceiveConnector | ft Name, MessageRateLimit



Solution:


We change the receive connector MessageRateLimit from 5 to 20, after that the issue was resolved.


Thanks & Regards,

Note : This will applies if you are using Barracuda SPAM & Virus Firewall in your Organization.


Problem:

User informed me he is not able to send (outbound)secured mail to external recipient with the subject Secure Me.(this mail is not encrypted, external user received plain mail without encryption).
Secure Me option is already enabled @ Barracuda Spam & Virus Firewall.




I verified all the settings, logs from Barracuda and also from Exchange Server and found that there is a send connector is created for the organization test-rs.com.



so that all the mails sent with the subject: Secure Me is not encrypting its directly delivering the message to the recipient.

Solution:
