SMTP hitting Google Auth too many times locking out emails

[wcbutler]

Hello all, long time Jaspersoft Studio/server user for my job.

My boss has a big push to have reports sent to all liaisons on my campus. As we have stacked up a lot of emails on 7am and 8am on the first of the month we are hitting the Google SMTP relay with a ton of auth requests and losing reports.

The team handling the gsuite said we can pay for an alt SMTP process that costs per email. Obviously I could also set up multiple Jasper servers or stagger the delivery time. 

Is there any way I can have the server auth once for SMTP delivery for a stack of emails?

I'm on Server 8.0.0,

 

Here is the error, I sanitized some GUIDS just in case

Can you try setting up the SMTP Pooling mechanism? or try other suggestions in the link posted below:  

https://stackoverflow.com/questions/40550149/smtp-error-454-4-7-0-too-many-login-attempts-please-try-again-later

This is something that you need to play/test as I don't have the same setup on my end.

I'll research doing this, if there is an article on the SMTP pooling that would be amazing.

Another idea, is it possible to resend on SMTP failure? I see a set of commented out misfire policy settings in quartz.properties
