Yes, the migration of your old messages into our archive is possible. Please note the following steps:
Export the desired messages and ensure that they are in .eml format.
Other formats such as .msg, .mbox, .pst or other binary formats are not supported during import.
Host the files on a website that allows direct access via an FTP/HTTP/HTTPS URL.
Please contact our support and provide us with a way to download the .zip file(s) (suitable for use with cURL/wget).
The .zip file(s) must be available for download. Physical storage media will not be accepted.
We will now process all data and add it to your domain's EuropeanMX archive.
There are many export tools that can convert your messages from the existing .eml format to the open source format. If it is not possible to provide the messages in .eml format, we can also set up an IMAP account for you, into which you can copy the e-mails from your mail client.
