How do I make Mozilla Thunderbird leave a copy of my messages on the server?
With Mozilla Thunderbird it's possible to leave a copy of each message on the mail server after you read it.
You'll want to do this if you read email in Mozilla Thunderbird and another program (or our Webmail system). If you don't set up Mozilla Thunderbird to leave your messages on the server, it will delete the messages as soon as it connects to read mail, and the other program (or Webmail) won't be able to see the messages.
You can also do this if you want your old incoming mail to be permanently stored in our backup system (see "E-mail backups" on our backup policy page for more details).
This page explains how to set up Mozilla Thunderbird to leave a copy of each message on the server. It assumes that you have already followed the basic instructions to set up Mozilla Thunderbird.
