Problem with domain email

Hello,

I used to have wp.com which I recently transferred to wp.org. With my wp.com blog I had a domain name (penseesduneshoesaholic.com), which was transferred on my wp.org blog. The domain was renewed yesterday. I also used a redirection of a custom email, tatiana@penseesduneshoesaholic.com, to my regular email, tatianamk23@gmail.com.

Since this morning, the redirection hasn’t worked. I am not getting any emails (I use this email a lot so this is very very problematic). It’s not an issue of my mailbox because when I email tatianamk23@gmail.com it works. Does it have anything to do with the domain name renewal? Where do I check? Now that I have wp.org everything is different…

Thank you in advance.
