In Symantec Messaging Gateway appliances, the web Graphical User Interface (GUI) has a configuration page where the appliance can be configured to allow e-mail addresses to contain the % character, 8-bit characters, such as "+", and to start an e-mail address with a dash "-".
The configuration page can be found under Protocols->Settings, on the "Settings" page, under the "Address Validation" section. Each setting can be enabled with a check mark and disabled by removing a check mark and then clicking on the "Save" button at the bottom of the page.
The settings are:

Allow email addresses to start with a dash
