If you receive a message with an attachment RocketMail will display the attachment's file name and type when you open the message. By simply clicking on an attachment we could either save the file to the disk or launch the associated application. RocketMail limits storage to 3MB, but warns you when you have exceeded your storage limit. We had 3.4MB stored and were asked to delete unnecessary messages when we logged in. Unlike HotMail which will only warn you so many times that you are out of storage, RocketMail won't delete your old messages.
