I have configured email setting with smtp.gmail.com:25 (Checked with 465 & 587) , enabled ssl and got email alerts for past few days.I didn't get any email from yesterday and I have checked the splunkd.log it shows the below error.Let me know how to resolve this issue.
ERROR:root:(454, '4.7.0 Too many login attempts, please try again later. t15-v6sm241001qke.74 - gsmtp') while sending mail to: kavin@xxx.com
