You can edit the default noreply@yourdomain.com email address that will appear in the password reset emails by editing the configuration file config/config.ini.php, and adding under the

[General]

section, the following line:

login_password_recovery_email_address = "info@example.org"

All password reset emails will now be sent from “info@example.org”

You may also change the email sender name by setting:

login_password_recovery_email_name = Piwik

and you may also change the Reply-to email address and name:

login_password_recovery_replyto_email_address = "no-reply@{DOMAIN}"
login_password_recovery_replyto_email_name = "No-reply"
