Most commonly, this happens when received emails have one or more attachments that are too large to download with dial up, using Outlook/Thunderbird. The emails get “stuck” and when you try to get your messages again, the server starts sending you all the messages over again.
There are a couple quick fixes you can do, you can either login through our Webmail to delete/move the email from the inbox, or temporarily use a highspeed internet connection to quickly deal with the issue. If you do not have access to highspeed internet, we do have two public computers that are available at our office on 280 – 111 West Hastings St.
