not receiving a confirmation email from Trello

[vitaly]

I'm not receiving a confirmation email from Trello and I can't solve the problem.
I've already checked my spam folder.
I've already made sure I entered the email correctly.
I've already checked if my email is working correctly.
I've already tried sending myself a test email or an email from a different address.

My email  resar@email.ua

Hi, Vitaly!

Checking our email logs, we're facing the error:

smtp; 451 Unauthorised request. Try again later

This is usually related to a mail server issue or greylisting. Can you please go through https://support.atlassian.com/trello/docs/not-receiving-confirmation-emails-or-password-reset-emails/ and add the mentioned addresses to your allowlist?
