Mailscanner and Base64

Hello Jerry,

I downloaded the v4.85.2-3 RPM for Redhat/CentOS and used its included installer. However, I still get the same issue. 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). 

Thank you,

I would suggest doing a fresh install using the included installer for your test.
