PDF Woes

[Julian Field]

The problem is caused by the fact that you should never send PDF docs as 
quoted-printable. Quoted-printable is designed for files that are mostly 
text, and in which the end of line sequence doesn't really matter. 
MailScanner legitimately takes the attachment apart from the message, and 
then has to rebuild the attachment on the message's way out. Following the 
allowable end-of-line sequences in quoted-printable, a validly rebuilds the 
attachment. Unfortunately this ends up changing the end-of-line sequenence 
on one or two of the lines, which breaks the PDF file.

We did have a discussion about this a while ago. Look in the archives for 
"PDF" appearing in the Subject:.
