Configuring Attachment Blocking Targets Parent topic

You can block attachments according to a specific name or according to an attachment type. ScanMail Mobile determines attachment type by the file name extension and true file type. Block attachments with two general strategies: either block all attachments and then exclude specified attachments or specify all the attachments to block.

    The Attachment Blocking screen displays.
