Please tell me what could be the problem?

Answer 1

Are you asking what's the problem?
I'll tell you what the problem is.
Here is your problem - you are using the ancient mail.php protocol.
It has been blocked in Google and in mail-ru for five years.
Two solutions:
1. Do letters come to Yandex? Well, use Yandex!
2. Yuzay SMTP, here is a chic lib - https://github.com/Ipatov/SendMailSmtpClass
And no domain settings and other rubbish are needed !!!
And by the way, there is a built-in SMTP in Bitrix!!! Newbie sho?))

Answer 2

mail servers are turning off your mail, configure MTA correctly, check if you are blacklisted

Answer 3

In addition to the server, DNS may not be configured correctly. Use SMTP. There is a module in the market .
