Andrew is the Exim expert. Let’s see if he has an opinion. Thanks for testing this by the way.

Its very clear: in the spool prior to MailScanner scanning the file, the exim -D file will have the original length of each base64 encoded line. Once MailScanner scans the file, the version of the exim -D file copied to the outgoing spool changes each line to be 60 characters long (all the data is preserved so the file has more lines).
