For example, MTAs that autoconvert from quoted-printable to 8bit, a
rather common circumstance.
I did the following Content-Transfer-Encoding failure analysis:
Failure rates for message top level encoding type
+--------------------------------------------------------+
| enctype total bodyfail pct |
|--------------------------------------------------------|
| 8bit 31 25 80.6 |
| 5461 1236 22.6 |
| binary 5 1 20.0 |
| quoted-printable 1188 179 15.0 |
| base64 32 3 9.3 |
| 7bit 1465 106 7.2 |
+--------------------------------------------------------+
Based on my PCN, 8bit does have a high rate of failure, but they are a
very small amount of the grand total. The encoding types; QP, base64
and 7bit offers the better lower failure rate. Except for the 3
base64 fails, but I can't tell if they originated that way or not. I
will take a SWAG that these represent direct messages and were not
going thru a list.
It would be interesting to see what Murray can show for his volume
collection.
