Because the content of the attachment, as well as any header, will be used to check the RFCReader match.

Check the full source of the message in rfc822 format. Each line, one by one, will be examined to be matched against the strings on the RFCReader page. If there's a match, the message will be rejected with the "content is not acceptable here" error.

Okay, I removed everything that could be an issue from the Body and Subject.

If sending only an attachment with no text or subject how is it the RFCReader reading it to bounce it back?

Thanks in-advance for any help...

Attachments from senders are getting the error below... I had them send the same attachment to my .mac account and it worked fine. I changed the name on the attachment with no text in the body or subject line and it continues to get bounced back. I know its not a size issue.

Any ideas?
