SMF 2.0.15 don´t sent email and activation link to new member

[Testi2021]

Our SMF 2.0.15 forum transfered to new address and everything seems to be fine, but now I found that new members don´t get any email with activation link.
Same problem is also with forgotten password. No email to them. I tested that my self by testuser.
Where I could find the reason?

Maybe try to upgrade your forum to the latest version SMF 2.0.18
