Can't purchase due to incorrect email domain checking on eshop

Hi, I am attempting to pre-order the Trezor Safe 3, however the eshop payment site has an incorrect email filter / regex / etc.

My email address is not being accepted. This TLD has been valid for almost 10 years now: .solutions - ICANNWiki

Hi @warez,

we tried to enter your email with no issue. Our regex does not check TLD. However, there is a DNS domain check, so the check may fail if there is a DNS issue. May I ask you to try again (you can try in incognito mode)? Also, please try using a different browser or computer/phone. Let us know if the issue persists.

What does the dns check? Whether or not there’s an MX record?
