Well, your server does treat it different from all the other folders, in
that it does not allow to "put" any mail there. If you move a mail from
your INBOX to your spam folder, offlineimap will not move the email from
one folder to another, but it will a) delete the mail from the INBOX and
b) upload the mail from the local Spam to the remote Spam folder as if
it were a different mail. And that uploading to "Spam" is what dovecot
seems to object to.

That would make sense. Still not sure how we should cope with that situation.

Thanks, that's what I needed, we should probably collect server quirks
on some wiki page or so?
