Hello,
i found that our DEVICE (WorkCentre 3325) sending mails with MIME header
Content-Type: MULTIPART/MIXED;
by this way the mailenable's webmail cannot open mail's attachments sent via DEVICE (WorkCentre 3325) , just shows text content.
whenever i changed its Uppercase form as lowercase with a texteditor everything fixed…
Content-Type: multipart/mixed;
but we have lots of domains and users to fix it each time... can mailenable developers fix this problem showing attachments of mails with uppercase header MULTIPART/MIXED
