ATT00001.htm shows up along a Mail attachment

Every time I send email with an attachment, a strange file with the name like "ATT00001.htm" shows up along EACH attachment at the recipient's end.

This is very annoying and confusing to the recipient.
How can I prevent it from happening?

MacBook Pro 17-inch (June 2006), Mac OS X (10.5.5), G5 Dual 2GHz Tower (Sept. 2005)

Kunio,

Is this account on an Exchange Server?

I get emails with these sort of attachments from friends using MS Outlook and MS Windows Mail. I think it relates to their use of Rich Text Format vs Plain Text.

I don't see them on anything I send, even when sent in RTF.

Test your issue by sending a message in Plain Text to see if these attachments persist -- to assure only Plain Text for the test, Compose the message, but before sending click on Format in the menubar and choose Make Plain Text.

I send email thru a non-Exchange SMTP server, but yes, I receive email thru an Exchange server.
Both are at work.

I just did a test you suggested:

[1] Send email to myself as Plain Text with a PDF attachment.
The received email has the PDF file and a plain text file "ATT00001.txt"

[2] Send email to myself as Rich Text with a PDF attachment.
The received email has the PDF file and a file "ATT00001.htm"

So, either way, I end up with an extra file that I did not send in the first place.
How can I make this stop?

Kunio,

I have received your test message, and have responded with a screenshot of what I received (which contained only one attachment -- the intended PDF), and another displaying your original message in Raw Source format.

The latter message was Bcc'd to another of my email accounts, and when received there has no attachment whatsoever. Let me know if there is any extraneous attachment on your copy?

I had the same problem. I found a plug-in that got rid of that problem and a couple other problems I was having with attachments when sent to non-Apple mail users. I installed the plug-in yesterday and the superfluous empty html attachments are gone. Check out "mail attachments iconizer" I wonder why Apple has not fixed this problem? I had recently upgraded to Leopard and have seen it in both 10.5.4 and 10.5.5.
