APPLIES TO

- Microsoft Mail Gateway to SMTP 3.0

This article was previously published under Q118595

## SYMPTOMS

The Microsoft Mail Gateway to SMTP attempts to uudecode an incoming message (or attachment) that is not uuencoded.

## CAUSE

To determine the presence of uuencoded text the Gateway parses the message and looks for the word BEGIN at the far left of a new line, followed by a blank, and END at the far left of a subsequent line. Uuencoded text is marked at the beginning with the phrase BEGIN UUENCODE and at the end with END.
The word END can actually be a part of another word, such as ENDEAVOR, and if the Gateway finds BEGIN at the start of a new line, followed by a blank, then END at the start of another line, it considers the text in between to be uuencoded and tries to uudecode it.

## RESOLUTION

None.

## STATUS

Microsoft has confirmed this to be a problem in the Microsoft Mail Gateway to SMTP, version 3.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
