I have another question about transferring e-mails from the old mail server to the new “mailcow”.
The old and new server are the same domain.
How to start configuring emails if the old server is still working, how to transfer emails to the new server if it is the same domain?
The old mail server runs on postfix.
That’s why I kept asking how I could get to the emails to read them, because if Postfix had been installed in the same way, I would have transferred the messages to the mailboxes with normal rsync, but it’s not that easy and I don’t know how to do it.
Please help.
