You receive multiple copies of the same email message in your email software.
The most common cause of multiple e-mails is configuring your POP client (eg. Outlook, Outlook Express) to leave copies of your e-mail on the mail server.
Every time your e-mail program checks for new messages it makes a connection to your mail server and has look at what is there and compares it to what you already have on your computer. After it does this, it is supposed to download only the new messages. However, if the mail headers stored on your computer become malformed or corrupt your mail program does not know you already have the message and downloads it again.
Before checking your email via your POP client, log into your e-mail using DomainsFoundry webmail (http://mail.domainsfoundry.co.uk). If you only see one copy of the message in Webmail but you see multiple copies in your e-mail program you can be sure that the problem is with your mail program.
The quick fix for this is to change the setting that causes your mail program to leave a copy of mail on the server.
In Outlook 2003:
1. On the Tools menu, click E-mail Accounts.
2. Click View or change existing e-mail accounts, and then click Next.
3. Select your DomainsFoundry account, and then click Change.
4. Click More Settings.
5. Click the Advanced tab, and under Delivery, uncheck the Leave a copy of messages on the server check box.
6. Click OK, and then click Finish.
The next time you Send & Receive, it should only download a single copy of each message.
