Laravel - disabling SMTP errors

I'm sending emails in my production using google apps for work email. it is written that I have exceeded my quota, and it breaks the website. I get the following error: Swift_TransportException in AbstractSmtpTransport.php line 383:Expected response code 354 but got code "550", with message "550 5.4.5 Daily user sending quota exceeded.XXXXXXXXXXXXX - gsmtp"

how can I disable this exact error? I'm going to find a solution to fix this problem but meanwhile I must prevent this from happening. Thank you all in advance Yossi
