Issue/Introduction

When an email is sent that is bigger than the maximum file size specified in the Email Security.Cloud portal, the email will be blocked by Symantec. By default, the sender, recipient and the anti-malware administrator will receive a notification about an email exceeding the size limit.

Email Size Limit

 

 

 

Cause

Emails are blocked due to email size limit configuration in the Email Security.Cloud Portal.

Resolution

To change the maximum email size limit follow the steps below on your Email Security.Cloud portal:

  • Navigate to: DashboardPlatform > Message Size
  • Change the size
  • Click Save
  • Allow about one hour for the change to take full effect before you will be able to receive emails upto the new size limit

The email size that the ClientNet portal uses is based on the final size of the email, post expansion. See Maximum email size settings for Email Security.cloud for more details.
