Configuring sendmail with gmail is fairly easy.

If you have 2-step verification enabled in gmail then you'll have to create an application-specific password.

I have to config sendmail/postfix relay via Gmail, and config fail2ban use sendmail/postfix?

Configure a mail client to use gmail (in my previous post I outlined configuring sendmail). Then once you have the mail client configured and successfully sending test emails then you should modify /etc/fail2ban/action.d/mail.conf and modify the commands to utilize the mail client.

So on the github page for mail.conf they use simply the mail command. You would need to change that mail command to sendmail (with sendmail specific options) or you would need to configure the mail command to work with gmail.
