I am having issues tracking down a problem.
In my admin panel I am seeing the following message
```plaintext
Some problems have been found with your installation of Discourse:
* Email polling has generated 4 errors in the past 24 hours. Look at [the logs] for more details.
```
on /logs I am seeing
5 Job exception: -ERR [AUTH] Username and password not accepted.
This is the backtrace data

```
I have verified using ruby net/pop that my credentials works. The polling interval is also set to 5 minutes and it has only failed 5 times in 24 hours. It has been happening for about 2 days now and I am just not having any luck tracking down the issue.
Anyone have any suggestions?

If your e-mail provider is intermittently failing to accept the username and password given to it, you probably want to talk to the operators of the e-mail service.

I will be contacting google as well since this is a gmail account. I have been digging through the logs on the server and I can not seem to find an entry for these errors in any of my logs so I do not have timestamps for each instance of a failure that I can take to them. I am hoping I am overlooking a log somewhere.

If it’s a regular Gmail account then using it to deliver Discourse email is a violation of Google’s terms. I think it should work for G-Suite, however.
You’ll almost certainly be better off with a service like Mailgun.

I am using G-Suite, I believe I have been able to resolve the issue by increasing polling interval.
