We use Zimbra OpenSource 6.0.5 CentOS5_64, multi servers.(1 master ldap + 2 mailbox servers + 1 proxy & mta )
There are some questions and anyone helping answering would be appreciate。
1.when uploading a file larger than zimbraFileUploadMaxSize to Briefcase, the process moving several seconds and then just stopped at the upload window, no errors prompted and no operation can be done（no closing the window nor canceling the process...） I have to refresh the explorer to re-login the mailbox. why zimbra doesn't feedback some info such as exceeding Maxsize? It's not so friendly~
2.Some of our users upload file(less than 10M) through ISP network with uploading speed roughly 512k, it's hard to success. I have tested uploading 1M,2M...10M to the mailbox, files less than 5M uploading success rate ok，but more than 5M usually after 3 or 4 minutes it's just stopped like I mentioned above（the first question）. With the Standard (HTML) version, it would display a "not found" page. But I can upload all to our old email(Openwebmail) successfully. were there some timeout settings ? I read the thread "[SOLVED] Uploading large files to Briefcase... timeout?", having something similar but not totally. There is no error in log files，and I can't find the parameters mentioned in the thread.
All the uploding done from the proxy server, is there some relevance?
3.The zimbra Standard (HTML)version doesn't support IE6.0 ? Especially uploading attachment, the upload frame can't display.
4.Single email download. Our user have some suggestion, he want to download some important email when he reading it.I told him to do that from the Import/Outport function, but it's not so convenient to filter the email that he wanted. A lot of email system can download the email at the reading email window. I hope Zimbra can add this function.
The Zimbra is very good, I wish it's getting better~
