Moved Domain. Took a week. Missing emails.

Hi!

So I moved a clients domain from one provider to another. Everything is working as it should, no problems.

However, due to a screwup by Godaddy (old provider) the transfer took 10 days. My client is missing all her emails she was expecting during the transfer. Is there a way to retrieve the emails sent between May 8th and May 18th?
