How to set up mail in VMBitrix?

Question

1C-Bitrix

Good day to all!
There is VMBitrix and there is a need to configure sending mail from Bitrix.
I made settings for Yandex Mail, but in the end I get an error when sending and this is the entry in the log errormsg='the server sent an empty reply' exitcode=EX_PROTOCOL

Here is my .msmtprc

account default
logfile /var/log/msmtp.log
host smtp.yandex.ru
port 587
from [email protected]
keepbcc on
auth login
user [email protected]
password secret
tls off
tls_certcheck off

Tried to put the 25th port, the error remains. I tried to put 465 with tls on, sending just hangs and that's it

Answer 1

Here's how it works with Yandex:

account default
logfile /var/log/msmtp.log
host smtp.yandex.ru
port 25
from [email protected]
keepbcc on
auth login
user [email protected]
password *********
