Hi,

I have a strange issue, at one user the attachments from a part of the messages have 0 bits on webmail interface but downloaded with Outlook the attachments can be seen/accessed. The senders are various, others in CC or TO field can see the attachments in both webmail and Outlook (2007). The attachments can be .jpg, .xls, .html, etc.. no pattern.
It doesn't matter the browser (IE 8 and FF 3.5), Windows version (tried XP Pro and Vista Business).
Also tried AJAX and HTML interface on webmail, tried another theme and default one, the same thing.
I'm running Zimbra 6.0.4 on Ubuntu 8.04 64bit.

No space issues on the hdd, all services are running..
Also the user receive messages with attachments from various senders and attachments can bee seen/downloaded from webmail. The COS doesn't have Disable attachments view checked.

When I try to forward the message from webmail if I don't uncheck the attachments (which have 0 bit) I can't send the message, the following error found in mailbox.log:
