1s Bitrix, problem with mail?

Question

1C-Bitrix

Hey guys, this is the situation.
I will send mail from Bitrix via smtp using cutom_mail.

There are no errors, it says sent.
Y is also in b_event, everything is ok.
I look in the dispatch logs, it’s not the addresses themselves that come to the address, but #MAIL_TO#, that is, Bitrix did not substitute my data.

What could be the problem?? This is the first time I've encountered this. And changed filters and # and without them. That is:

Bitrix 15.06 was not like this before, everything worked.

Answer 1

You don't need to put # in php code. Only in the mail template itself.
"EMAIL_TO" and "EMAIL_FROM"

Answer 2

you are fundamentally not sending mail
according to RFC correctly, there are no Russian characters in the headers and require encoding
