Sending Multiple Attachments with Email Report Server

From Support

To attach more than 1 report to an single email:

The only way is to use the MAILOUTQ command which pretty much needs to be called from a program. With that command you can choose which reports you want to go like all reports with a certain spool name or user data etc., just like setting up an email recipient. Prompt on MAILOUTQ and you will see the settings.
