hi,

I've got a very strange behavior: I uploaded old mails from a local folder (thunderbird / osx) to my Dovecot (Debian Squeeze) and now, the iphone (ios6) show the oldest mails first. The only thing I can imagine is, that Dovecot got from Thunderbird the newest mails first and last the old mails, so that in the last mdbox are the old one.

Probably.

So, if it is correct, how can I fix it?

If iPhone can't sort mails by received date, then I don't know if there's any really easy way to fix it. Basically figure out some way to import the mails again in the correct order..
