Your email will not be deleted from your POP3 server after it is displayed. You may reread your mail as often as you want.
Please give my system long enough to talk to your email server and begin to display the results to you. You will begin to see your email while my system is still retrieving it, so continue to move down as more arrives.
At the present time any attached files are included in-line. Some browsers know how to display these files, so you should only have to "save as" to save them to your local system. If the files show up uuencoded then you're on your own for now. :-)
