The information in this article applies to:
- Microsoft Exchange Server, versions 4.0, 5.0, 5.5
-------------------------------------------------------------------------------
SYMPTOMS
========
If you submit a message that has a Base64 body part to Exchange versions 5.5 and
earlier by using Post Office Protocol 3 (POP3), and the body part contains
extraneous characters after the termination sequence, you may receive the
following error message even if the extraneous characters are otherwise valid:
The Microsoft Exchange Server received an Internet message that could not be
processed. To view the original message content, open the attached message.
<<message.txt>>
CAUSE
=====
Exchange only accepts Base64 encodings that are multiples of 4 in size. The
extraneous characters cause the encoding size to not be a multiple of 4, so
Exchange rejects the encoding.
RESOLUTION
==========
Do not append extra characters to the end of a Base64 sequence that is submitted
to Exchange.
STATUS
======
This behavior is by design.
