SMTP: response code "235" but got code "535"
This is probably more a PHP error, but I came across it in the context of bookstacks.
When configuring the .env file to connect to a mail server, and testing the email, you might get this error:
unexpected response code "235" but got code "535", with message "535 Error: authentication failed".". Authenticator "PLAIN" returned "Expected response code "235" but got code "535The problem goes away when you put the password in quotes a such:
MAIL_PASSWORD="thIsIsYour873#password"
