MODIFYING MAILING LIST SETTINGS
This page allows you to change the information stored in the mailing list profile. Simply do the following:
Tick the Yes radio button to enable, otherwise tick No .
Setting the option to Yes will remove all Return Receipt and/or DSN requests before they reach the list subscribers.
For lists where either the recipients are using older non-MIME compliant readers, or if the nature of the list is entirely text based, non-MIME digests can be used. For all other applications, especially where structured messages including HTML and other rich text formats are used, or if attachments are common, the MIME digest type is recommended.
Set the MIME digest. The default is enabled.
Click the Update button.
