You are using the wrong hostname...when configuring emails it'd be wise to consult your email provider's documentation for the correct information to use. If you did you would've seen that the hostname for Gmail SMTP is actually smtp.gmail.com; not mail.gmail.com.
smtp.gmail.com
mail.gmail.com

me sigue rechazando la autenticación en ambas pestañas
Then it appears Gmail is forcing Modern Authentication (OAuth2) on your account. You'll need to download and install the OAuth2 plugin and follow the guide below to setup Modern Authentication (OAuth2) for Gmail:
he seguido las instrucciones tal cual la guía y me arroja este error
I can’t read Spanish, can you possibly translate it for me?
If you are an osticket developer, check the details of the error
Apparently Google doesn't allow private ip addresses for OAuth2. You'll either need a public IP or fake a domain name in local DNS. I believe you can use localhost as well but that means you’ll have to access the site from localhost.
