[imp] problem displaying attachment

[Horde at CLU]

Hello,

When mail comes into user's mailboxes, it is scanned using Spam Assassin and Mail Scanner.  If the email scores high enough points, MailScanner determines the message is spam and modifies the subject line to let the user know this might be spam.  There have been a few users that have been sent hotel or airline confirmations that come to them possibly identified as spam.  When the message is viewed however, there are no attachments.  If you click message source it is possible to view the whole message without any formatting.  If you forward the message to a yahoo/hotmail account, it shows the forwarded message has an attachment and you can view the original attachment with formatting.  

If anybody has experienced something similar to this or can share any ideas of how to resolve this, it would be greatly appreciated.

Thank you,

Kevin Appel
