Setup Mail Using Google Servers

 

To setup mailing using Google's free mail server, ensure that your .env settings within your bookstack directory ( /var/www/bookstack/.env ) contains the below.

APP_URL environment variable must lead with http:// OR https:// and end with /
such as http://website.com/ OR https://website.com/
Any form of the following will cause URL redirect issues:
www.website.com OR website.com OR subdomain.website.com

# The below url has to be set if using social auth options
# or if you are not using BookStack at the root path of your domain.
APP_URL=https://knoats.com/

#Mailsettings
MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=email@gmail.com
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls
MAIL_FROM=email@gmail.com

Test sending mail with the commands below -

echo "This email confirms that Postfix is working" | mail -s "Testing Posfix" emailuser@example.com

If you have a firewall, be sure you open the port you enter on line 9 for MAIL_PORT

You must have HTTPS certificate and loadbalancer configured, if you are using DigitalOcean. See the links below.
