How to set up sending mail from the bitrix portal?

Question

Email

There is a centos virtual machine, someone installed the Bitrix portal in it and connected the gmail box from which the portal sends mail, you need to change this box to another one.
Installed postfix, corrected configs - sent from the console, everything is OK, started the system check from the admin panel, looked at the logs (cat /var/log/maillog) - everything is gone
I send from the portal (from the crm module) - the logs are empty if you open the log msmtp sends via gmail, if I specify the settings of the desired new mailbox in msmtp, it does not send at all.
in /etc/php.d/bitrixenv.ini sendmail_path is changed to sendmail -t -i [email protected]
Where to dig? where else can sendmail_path be replaced?

Answer 1

After updating the portal, everything worked, mysticism.
