Summary	0001521: Webbrowser freeze with large mail folders
Description	When a mail folder has many emails in it, the webbrowser can freeze because in background all mail headers are retrieved by the UI. We had this night the case where a server did go crazy and did fill one mailbox with 500k mail messages. When we open that mail folder in sogo web ui, then the folder is displayed and the first headers are shown correctly and we can start working with it. But then a few seconds later the web browser (Firefox 8.x) gives a warning about unresponsive script and then completely freezes.
Additional Information	It looks like the js ui does retrieve all mail headers in background. When there is a huge amount of mails in a folder, this can lead to all sorts of problems, mailny resulting in a unresponsive browser. Sogo should use a paging system to only retrieve partial message lists as needed. (Thunderbird 3.1.x has a similar problem)

When you have a very large number of mailboxes, it's still slow in v3, but not when you have a gazillion of messages. We are working on the large number of mailboxes bug.
