When transferring a domain to us, we offer a simple option for transferring existing e-mail inboxes. All emails, including attachments, are transferred to the email accounts with us. The folder structure is also retained.
The emails are copied during the transfer and remain in the mailbox of the previous provider. No emails are deleted during the transfer!
E-mails are transferred from the previous to the new mailbox via an encrypted connection (if supported by the previous provider). The individual emails are only stored in the server's RAM for the duration of the transfer and are not stored temporarily.
Important notes
Some e-mail providers have an upper limit set for the display of e-mails via IMAP. With Gmail, for example, you can set the limit in the IMAP settings. No limit must be set so that all emails can be transferred.
Access to the mailboxes by external applications must be permitted. If necessary, read the documentation of the previous e-mail provider or contact support.
The previous provider must support the retrieval of emails via the IMAP protocol. The POP3 protocol is not supported by our tool.
In the following video instructions, we show the transfer using the example of a Google Mail account:
Step-by-step instructions
1. create target mailbox
If you do not already have one, create a new email account in your customer menu. Make sure that this mailbox is at least as large as the storage used by the previous email provider.
Please note: the maximum mailbox size with us is 10 GB. The total storage capacity available for emails depends on the hosting package you have chosen (e.g. 10 GB in the BUSINESS package, 30 GB in the PREMIUM package)
2. call up the mail transfer script
Go to the website https://mailtransfer.jweiland.net/.
Select your current e-mail provider in the left-hand area (1).
If your provider is not in the list, select "Manual entry". In this case, you will need the incoming mail server (IMAP) and, if applicable, the IMAP port of your provider. You can usually find this information on the provider's website.
Then enter the previous e-mail address and the password for the e-mail address (2).
Then enter the e-mail address and password of the target mailbox in the right-hand area (3).
Optionally, you can use the "Add another mailbox" button to specify one or more other mailboxes that should also be transferred (4).
Then click on "Next" (5).
3. folder selection
You can now decide whether the content of the entire mailbox or only individual folders should be transferred.
If you only want to transfer certain folders, click on the "User-defined directory selection" button.
After a few seconds, you will see all folders of the source mailbox in the right-hand area. Select the folders you want to transfer by activating the checkboxes.
Note for Gmail users:
the "All messages" folder does not usually need to be transferred as it contains both received and sent emails.
5. transfer order has been accepted
On the following page you will receive a link to the status monitor of the transfer order.
From now on, the transfer will run automatically in the background. You can check the progress of the transfer at any time in the status monitor.
You do not have to remain at your PC during this time and can close the browser or switch off your computer. In this case, however, make a note of the link to the status monitor.
You can copy the link to your clipboard by clicking in the text field (1).
Alternatively, you can also open the Status Monitor directly by clicking on the button (2).
6. status of the transfer
You can see the current status of the move in the status monitor.
This page is updated automatically every 30 seconds.
Please note:
New emails that were received in the source mailbox between the start and end of the move may not have been transferred. In this case, simply restart the move.
7. transfer completed
At the end of the transfer, you will receive a corresponding message in the status monitor.
If problems have occurred during the transfer, you will see corresponding information here.
Then check carefully whether all emails have been transferred. If this is not the case, you can simply start the transfer again. Emails that have already been transferred will not be transferred twice (1).
If all emails have been transferred correctly, delete all data associated with the transfer job from our system (2).
Transfer a large number of e-mail accounts via bulk import
To conveniently transfer a large number of email accounts, our mail transfer service offers the option of importing a CSV file with the corresponding account data.
This allows you to transfer dozens or even hundreds of email accounts "in one go".
We show this process in the following video instructions.
2. upload CSV file
Select the CSV file in which the email accounts are stored (1).
If required, you can adjust the column delimiter of the CSV file; the default setting is a comma (2).
You can also download a template to help you adopt the structure of the CSV file (3).
5. select the folder to be transferred
By default, the entire content of a mailbox is transferred. If required, you can select which folders are to be transferred for each mailbox individually.
To do this, click on the "User-defined directory selection" button.
You can then select the folders to be transferred by activating the checkboxes.
Note for GMail users: as a rule, the "All messages" folder should be excluded from the transfer.
