1C-Bitrix. When registering, users do not receive a confirmation email. How to fix it?

Question

1C-Bitrix

Good afternoon
I checked the boxes in the Main module so that an email confirmation email is sent.
Post template made. Activated.
But the letter does not come ...
And in principle, the registration letter with the data is not sent
. What are the reasons? Where to dig?
Thanks in advance
PS Email sending works. Password recovery sends an email.
