Only when you fail to abide by email RFCs and generate message bodies
with lines longer than ~990 bytes. The correct thing to do when sending
long lines is to use the "quoted-printable" content-transfer-encoding.
Postfix folding of long lines is substantially more graceful than
Sendmail's which not only folds the line but also inserts an extra
"!" character into at the end of the folded physical line. The Postfix
algorithm is less likely to do damage to text content, but clearly
HTML mark-up may not always survive the transformation.
The fix is your hands.
