BitrixVM 7 - how to set up msmtp?

Question

PHP

BitrixVM costs the latest version, letters do not always leave the server. More precisely, they are sent only through the command line with this command:
echo -e "test message" | msmtp --debug -t -i [email protected]
And when I use PHP's mail() function, nothing happens. More precisely, I write it like this:

if(mail("[email protected]", "TEST SUBJECT", "TEST BODY"))
echo "Почтовая система работает!";
else
echo "Неудача, почтовая система не работает, попробуйте еще!";

Writes "The mail system is working."

Answer 1

Have you configured smtp through the vm menu?

Answer 2

stupidly install sendmail and open port 25
