<email@example.com>: host gmail-smtp-in.l.google.com[188.8.131.52] said:
550-5.7.1 [184.108.40.206] The IP you're using to send mail is not authorized
550-5.7.1 to send email directly to our servers. Please use the SMTP
550-5.7.1 relay at your service provider instead. Learn more at 550

And from the google help center:
'The IP you're using to send email is not authorized...'
In order to prevent spam, Gmail refuses mail when the sending IP address does not match the sending domain. To send mail from your server to Gmail, we suggest using the SMTP relay provided by your ISP. Please note that we are unable to whitelist IP addresses or otherwise make exceptions at this time.
