# SMTP
**Authelia** can send emails to users through an SMTP server.
It can be configured as described below.
```yaml
# Configuration of the notification system.
#
# Notifications are sent to users when they require a password reset, a u2f
# registration or a TOTP registration.
# Use only an available configuration: filesystem, smtp.
notifier:
# You can disable the notifier startup check by setting this to true.
disable_startup_check: false
# For testing purpose, notifications can be sent in a file.
## filesystem:
## filename: /tmp/authelia/notification.txt
# Use a SMTP server for sending notifications. Authelia uses PLAIN or LOGIN method to authenticate.
# [Security] By default Authelia will:
# - force all SMTP connections over TLS including unauthenticated connections
# - use the disable_require_tls boolean value to disable this requirement (only works for unauthenticated connections)
# - validate the SMTP server x509 certificate during the TLS handshake against the hosts trusted certificates
# - trusted_cert option:
# - this is a string value, that may specify the path of a PEM format cert, it is completely optional
# - if it is not set, a blank string, or an invalid path; will still trust the host machine/containers cert store
# - defaults to the host machine (or docker container's) trusted certificate chain for validation
# - use the trusted_cert string value to specify the path of a PEM format public cert to trust in addition to the hosts trusted certificates
# - use the disable_verify_cert boolean value to disable the validation (prefer the trusted_cert option as it's more secure)
smtp:
username: test
# This secret can also be set using the env variables AUTHELIA_NOTIFIER_SMTP_PASSWORD
password: password
host: 127.0.0.1
port: 1025
sender: admin@example.com
# Subject configuration of the emails sent.
# {title} is replaced by the text from the notifier
subject: "[Authelia] {title}"
# This address is used during the startup check to verify the email configuration is correct. It's not important what it is except if your email server only allows local delivery.
## startup_check_address: test@authelia.com
## trusted_cert: ""
## disable_require_tls: false
## disable_verify_cert: false
```
## Using Gmail
You need to generate an app password in order to use Gmail SMTP servers. The process is
described [here](https://support.google.com/accounts/answer/185833?hl=en)
```yaml
notifier:
smtp:
username: myaccount@gmail.com
# This secret can also be set using the env variables AUTHELIA_NOTIFIER_SMTP_PASSWORD
password: yourapppassword
sender: admin@example.com
host: smtp.gmail.com
port: 587
```
