Probably because your Inbox is too big. If your Inbox is larger than 50 MB, webmail will be slow. To see how big your inbox is, ssh to shell and type "ls -l /var/mail/yourusername", where yourusername is your LPL username.
To dramatically improve your webmail performance, use your favorite non-webmail email client (e.g., pine, thunderbird) to create extra IMAP folders and save your Inbox messages to those folders. Once your Inbox is trimmed, keep it small by filing messages to IMAP folders frequently. If you can only use webmail to do create the folders and trim your Inbox, follow these steps:
- Click on folders and create a new folder. Sorry, but our system doesn't currently allow sub-folders.
- Go back to the Inbox (click INBOX on the left-hand side of the screen).
- Check the box next to the message(s) you want to move.
- Just above the messages, there is a drop-down list that has all of your folder names. Select the folder you just created, then click the Move button.
