Receiving third party email client shows attachment icon but no attachment is present


When sending email from the MailEnable web mail and receiving it in another client (e.g.Yahoo, Hotmail) it shows that there is an attachment when it is received but there is actually no attachment. 


This is due to the way in which a web mail message has been encoded. The issue is related to performance in the remote client in ensuring that a clients list display does not have to parse a complete message each time it is displayed in an inbox list display.  The MailEnable web mail client as with others will tag any email as a multi-part MIME message in the header. This is so that all clients know they can view the email in its desired format.

This same format and tag is used for attachments. This is the issue where the receiving client, rather than reading through the whole message, will only check the header tag of multi part MIME in the header and report that there is an attachment, thereby displaying the web mail attachment icon.
