If someone sends you a really big e-mail, you might want to leave it on the server or delete it rather than downloading it. The problem is that you can't get the other messages which are stuck on the mail server. You may also be the victim of 'mail-bombing'. That means that a sadistic mind sent you a lots of mail to "explode" your mail box. The only solution is to purge your mailbox. Mail Siphon provides an easy way to purge your mailbox or delete a specific e-mail without downloading the others.
