PDFing can delay sending files until all the spooled-files in a set have been received and converted. It then sends a single e-mail, attaching all the files in this set.
Each spooled-file in the set of spooled-files must have a “send to destination” value specified as: *SET*sssss, where sssssss specifies the set name. The last spooled-file of a set must also specify an email address (or addresses) as the “notify address” value. When the last spooled-file of the set is received, all the spooled-files saved for this set, will be attached to an email sent to the “notify address”.
