Blank email headers - email from Yahoo

[paulg7083]

Our company has 4 PCs all running Outlook 2003 - we have no server.
Each PC accesses the same email account at our ISP and each version of
Outlook is set to not delete email from the server. Consequently
everyone sees all the email for the company.

Our company has several clients who use yahoo to send us data files.
When received, on some PCs the emails are fine, but on others we end up
with blank sender and subject fields and the data is in hex in the body
of the email.

I have tested this problem as follows:

1. I accessed my Yahoo account and send email to the company account
with a small zip file attached - the email arrives as described above,
blank headers with the attachment in hex.
2. I have also accessed the webmail version of my personal ISP email to
send the same file to the company - this email arrived OK, headers and
attachment intact.
3. I also sent an email from my Yahoo account with no attachment - this
arrived OK.

Can anyone throw any light on this?

I have tried looking at the internet headers but nothing looks
obviously wrong (but then I am no expert).

Thanks in advance,

This is indicative of a poorly formed message on the sending side. Outlook
is fairly strict in its interpretation of the MIME standards for mail. If
headers are malformed or out of order, Outlook will misinterpret the
message.

I am surprised that a large outfit like Yahoo would not be following
proper standards when formatting outgoing email. Any comments?

You said that several client "used" Yahoo to send data, but what mail
applications do they use? Is Yahoo just the internet provider, or are they
the mail application provider as well?
