The following support article demonstrates how to set the message size of emails for a VPS. This is the limit set for both incoming and outgoing emails to the server.
- Once logged into Plesk, from the “Server Management” tab on the left, click on “Tools & Settings”.
- Under “Mail” click on “Mail Server Settings”.
- In the field for “Maximum message size” enter the value (in kilobytes) you require.
- Click “OK”.
You can now send and receive emails up to the new maximum message size.
