Hi,

I am using one of my email account to use SMTP as sender in a wordpress website. However, recently i found that it is not sending out to gmail. Then i check the log in Troubleshooting tab, i found lots of mails got exclamation mark beside some emails.

Those got the same error which is "Hourly Ratelimited. Captcha not verified"

I checked the log for this particular account only got 5-10 outgoing mails but what causing this issue? What is the hourly rate and how to solve this please?

I tried compose an email by using that account to gmail but it's working well.

Please help.
