SMTP with Authentication | Testing Command Verification

[Daniel]

Hello Everyone,

Can anyone confirm the below parameters placement are correct ?

My Case:

Configured SMTP Mail-Box through  App Password:

daniyaly...@gmail.com

The recipient address where I want to send email, alert notification or report:

daniyal...@gmail.com

• The Testing Command as per document section "SMTP server with authentication":

            echo "Test mail from postfix" | mail -s "Test Postfix" -r "y...@example.com"  y...@example.com

• The Testing Command that I modified as per my case:

echo "Test mail from postfix" | mail -s "Test Postfix" -r "daniyaly...@gmail.com"  daniyal...@gmail.com

Note: Please confirm is above placement of address are correct ? "-r" switch is used for return address and in my case the sending address is "daniyaly...@gmail.com" and I think it  should be return address also. Further in the very last is the actual receiver address  and in my case the receiver is "daniyal...@gmail.com".

Dear Wazuh Team,

Anyone there to help?

Hello Daniel,

Sorry for the late response!

In the command for testing your Postfix configuration with sample email, the format is as below:

echo "Mail Body" | mail -s "Mail Title" -r "recipient_email" recipient_email

The sender email has already been configured with credential at /etc/postfix/sasl_passwd file and not needed to be mentioned in this command. Therefore, in your example both the email address should be your recipient email address.

echo "Test mail from postfix" | mail -s "Test Postfix" -r "daniyal...@gmail.com" daniyal...@gmail.com

You should receive a test email in your recipient email after running this command, if you have already followed the previous steps properly as described here: https://documentation.wazuh.com/current/user-manual/manager/manual-email-report/smtp-authentication.html

In the next step, you need to configure the Wazuh Manager to send email notifications following this documentation: https://documentation.wazuh.com/current/user-manual/manager/manual-email-report/index.html

I hope it helps. Please let us know if you need anything else.
