This dovecot version is 7 years old already. Can you upgrade?

I have no idea how does this "Boxer mail client app" fetch message date.

Can you record some imap rawlogs to find out if it uses IMAP FETCH to get the message INTERNALDATE or does it really try to parse it from mail headers?

They do not rely on Date header. Date header is not mandatory and also it's not written on server side. It is written by the sender.
