Overview
For performance optimization, you can limit the size of the outgoing messages sent by users. By default, new users inherit settings from their domain. But you can change the settings for individual users.
Step-By-Step Guide
- In the administration interface, go to Accounts > Users.
- Double-click the user for whom you want to limit the message size.
- On the Messages tab in the Maximum message size section, select the Use custom settings for this user option.
- Specify the limit for outgoing messages for the user.
- Select Do not limit message size to disable any limits.
- Click OK.
Confirmation: The specified limit for outgoing messages reflects in the mailbox settings for the specified user.
