To directly answer your question, yes, you are going to have to go through them all to toss out the duplicates. It sounds like you have a slightly bigger problem at hand. If you keep getting the same messages over and over, it is because you're email box has become "clogged" with an attatchment, or just too many emails. This usually happens when you dial up to the internet. If you have a large email to download, say its message number 20, the first 19 will download fine, and then it takes 10 minutes to download the 20th email. OE times out while downloading this email, and will either freeze, or just stop downloading email all together. the "delete" command is never sent to the email server, because you have not fully downloaded all the mail. Now everytime you check your mail, you get the same 19 or so emails until it times out again. sometimes it'll get to number 25, then time out on that one, but the next time, you still have all of them to get. the best thing to do is to telnet into your mailbox, and see howmany messages you have, and delete any large ones, or call your ISP, and have them do this for you. If it weren't for users, computers would work just fine.
