Hi! We are having problem on sending email in ERPNext. We are currently using Gmail as our service. We are receiving this error.
(550, '5.4.5 Daily user sending quota exceeded. s76sm3343732pfc.35 - gsmtp')
Solutions we have tried but failed:
Changing the email in the Email account - It works for a while then the error will be back again
Retrying to send the email in the email queue - Error still exist
Turning on and off the “Allow Secure Access” in Gmail
Install a fresh server both Ubuntu 16 and 18
We are currently using Frappe v7.
Any help would be appreciated. Thanks
