After a transfer of the website on our servers, maybe you want to move your e-mail addresses and messages on our email server. Here you will find instructions on how to do this.
Transfer by using e-mail client (Mozilla Thunderbird)
If you are already using e-mail client that supports IMAP communication, this is the best choice for you.
First of all, you should add both your e-mail accounts into the email client to which you want to copy emails. For communication, you need to choose the IMAP protocol, which allows you to manipulate messages on the server. The procedure for adding an e-mail box is described in the Thunderbird mozilla e-mail client manual.
Switch to the e-mail account and folder from which you want to copy, and use CTRL + A to highlight all messages.
Right-click on one of the messages and select Copy to > Destination Box > Destination Folder.
Do a similar procedure with all folders or mailboxes.
