The presence of the WINMAIL.DAT indicates that he did not send in plain
text format. But it may be that the Exchange server is overriding his
settings. See the articles referenced at the link I provided before.

If messages are sent using the Exchange family of mail programs
(includes Windows Messaging or Outlook97/98/2000+) and the option to
use
Rich Text Format is selected, it puts the RTF message (and any
attached
files) in an attachment called WINMAIL.DAT (application/ms-tnef).
But
this attachment is useless to most other mail programs. In some mail
programs (e.g. Outlook Express), the attachment won't even be
visible.

The Exchange user can turn off the RTF option for messages to
selected
recipients. Note that if sending via an Exchange server, the
Exchange
server administrator may be overriding the mail client settings. In
this case, the administrator will need to make changes on the server.
In some cases, the Exchange server actually removes the attachments
to
some recipients.

For additional information, see the MS-TNEF WINMAIL.DAT Attachments
section of
Decoding Internet Attachments - A Tutorial
http://pages.prodigy.net/michael_san...de.htm#ms-tnef
At the above link is information on several utilities that can be
used
to recover the attachment if the sender can't or won't resend it in
plain text (or HTML) mode.

Have experienced several instances where a mail was sent to me with
an
attachment, but the mail I received had the attachment content
embedded in
the mail itself and no attachment was indicated.
The size of the mail reflected the included attachment but when
opened, only
the actual message displayed. The presence of the attachment data
could be
seen when looking under Properties Details Message Source. If I
Reply to
the mail or Forward it, the spurious attachment data is not
included
At present, all of these corrupted mails are coming from one sender
but that
sender has been able to send attachments OK in the past.- I am
currently
receiving mail with attachments OK from other sources.

Any suggestions ?

Thanks - Chris


Michael,

Thank you for that explanation - that would appear to be exactly what
is
happening. Looking at the "Message Source" in the Details tab under
Properties of the mail I can see the WINMAIL.DAT and ms-tnef
references as
follows :-
==========================
Content-Type: application/ms-tnef;
name="winmail.dat"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="winmail.dat"
===========================

I am waiting to hear from the sender to check if he is using the RTF
option - the Message Source indicates Outlook but I thought he was
using
plain text and can see a reference to that - is it possible to
identify that
anywhere in the message ?

Chris
