I'm getting the following error when opening an email with a file attached which happens to be an html file

"java.io.IOException: Error in encoded stream: needed at least 2 valid base64 characters, but only got 0 before padding character"

I googled this error and found a solution to do with javamail which I think zimbra uses partly the solution was to:

set javamail "mail.mime.base64.ignoreerrors=true".

However I don't know where I'd go about changing this setting in the Zimbra files.

Does anyone have any ideas?

Thanks.
