SMTP authentication is currently unsupported.
As a workaround, you send notifications using external script, which would send mail using mSMTP, for example.

Do you can show us this scritp?

And another, how i can use microsoft exchange or yandex mail or gmail for send email?

Please help me to configure email notification with msmtp.

I have another Debian mashine. Run this action:

#install msmtp
sudo apt-get install msmtp
#create msmtp config
sudo touch /etc/msmtprc
#edit config to
account default
host smtp.yandex.com
port 25
protocol smtp
auth on
from forexample@yandex.com
user forexample
password P@ssw0rd
tls on
tls_certcheck off

#recreate link
rm /usr/sbin/sendmail
ln -s /usr/bin/msmtp /usr/sbin/sendmail

#next to run recive message from cosole
cat test.txt | msmtp forexample@yandex.com
# and have a message from web interface:

От кого From   forexample@yandex.com
Кому         To   undisclosed-recipients
Когда         When   4 мая 2011 в 14:52

Server have this settings:
