Hello,
I have a problem with my emails. I use my domain to send emails of cases to clients.
My domain email is Google Workspace, but for some reason when I configure the outbound email account I can send like 10 emails and then I’m with this error.

I already tried Password for Apps, I tried the password of the account, disable the secure apps but the problem is always the same…

Hey there,

Are you still having issues with this?

I haven’t come across this myself, I’m afraid, but I’ve had a search around for that Error Message

I’ve come across a few suggestions, that might be worth giving a try?

Have you tried enabling Less Secure Apps for your Google account?
https://www.google.com/settings/security/lesssecureapps
There is also this post here, in which the user notes that changing his password resolved the issue:
Gmail "Too many login failures" in SugarCRM | How 2 Guru
There is also this post, detaiing that the Gmail Domain may need a DKIM:
g suite - Google SMTP Error: 454 4.7.0 Too many login attempts, please try again later - Server Fault

Unfortunately, as I can’t replicate, I’m not really able to investigate these solutions
However, do any of the above sound like a step in the right direction?
