Problem Description

Hi,

I configured an email alert with a long list of recipient emails. I added all of them via the cloud management page using Monitoring email whitelist. The problem is that some of them forget to act on the email they get and I have no way to know who have whitelisted it (I might be wrong here).

The behaviour is that the whole email action fails. It should succeed for the people who have whitelisted it and simply not send email to people who have not done so.

"type": "messaging_exception", "reason": "failed to send email with subject [Alert: We have some failures] via account [work]", "caused_by": { "type": "send_failed_exception", "reason": "Invalid Addresses", "caused_by": { "type": "s_m_t_p_address_failed_exception", "reason": "554 5.7.1 <careless.person@something.com>: Recipient address rejected: Access denied\n"

Regards

Steps to Reproduce

1. Create a simple email alert with two recipients.
2. One recipient should not confirm the email whitelisting.
3. The whole email action fails and none of the two recipient get the email.

Any updates on this? I'm using watcher email alert with 2 email addresses: one address has elastic email address: noreply@alerts.elastic.co whitelisted and the other one doesn't. The action fails with "reason": "554 5.7.1 <....@......com>: Recipient address rejected: Access denied\n". None of the recipients receive email alert.
