A uuencoded message attachment appears as garbled text in the body of a message in Exchange Server 2003

In Microsoft Exchange Server 2003, a uuencoded MIME e-mail message attachment appears as garbled text in the body of the message.

This problem occurs when a uuencoded attachment uses four digits to indicate the file mode. Exchange 2003 cannot parse these attachments. When four digits are present, Exchange 2003 does not recognize the attachment as uuencoded. Therefore, the attachment is rendered as garbled text.

After you apply this hotfix, uuencode attachments in four digits file mode are processed correctly.
