That I just install the 3.2.M2 I care of the Bug 8443 that sent a chinese
filename attachment have be resolved. This good, but I find when I forward a
mail with chinese filename attachment I find the filename also display a error
code. I juse see the Orignal Mail I send. I find this, when send a mail with
chinses filename attachment, the Orignal Mail like this :
Content-Type: application/octet-stream
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="=?utf-8?Q?=E8=81=8C=E5=91=98=E9=82=AE=E7=AE=B1=E5=90=8D( =E4=BB=A5=E6=9B=B4=E6=96=B0).xls?="

But When forward it to my Gmail , this Orignal Mail show in the Gmail like this:
Content-Type: application/octet-stream
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="LX

(弭�).xls"

So I guess that when Zimbra Mail forward the Mail with chinese filename
attachment not point out the use which encoding for filename . I think just
point out the filename encoding this bug will resolved. Thank !
