Found the answer - you change the "report_safe" setting in the file /share/spamassassin/10_misc.cf
By default, SpamAssassin moves the original message to an attachment. This prevents running dangerous scripting which may contain viruses and makes it easy for users to identify whether a message is spam before opening it. This option is controlled with the report_safe preference, which has three options described here:
report_safe 0 Don't Use Attachments – original message is unchanged
report_safe 1 Use Attachments – original message is encapsulated in its original format and added as an attachment (default)
report_safe 2 Use Text-only Attachments – original message is converted to text and added as an attachment
