Sorry if this is trivial (or if I’ve destroyed the internet), but I just signed up here today and am having some issues migrating IMAP mail from my old host.
I’ve set up a mail account here, and can read/send via Thunderbird. And I’ve started moving mails over both via Thunderbird and IMAPsize. But where do the actual mails go? My Maildir and subfolders are empty, although I have no problem seeing them in Thunderbird.
