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
