There is customer service department send a mass mail with attachment to their customers.

They will put all clients' email to "Bcc" and sent to them.

When we get this mail, we find there is no attachment in it.

The property the mail file is as below:

from="sender@aaa.com" to="*** Email address is removed for privacy ***" size=995805 filters="rbl_Spamhaus[0],cmae_smtp_6

From web mail,we find attachment. There is attachment in Outlook 2007-2013(win7),,Thunderbird(win7), Outlook Express in XP .....

If the mail client is Microsoft live mail 2009-2011(win7),, There is no attachment in live mail....What is the problem????
