Watcher does not accept my Mail

[kainico (Kai Horvath)]

Hi all,

I discoverd an issue where elastic is not sending alerts to my Email Adress.
I have tested this with multiple alerts that work just fine with other Mails.

Alerts are not even sending Mails to different Mail Accounts if my Mail is in there.

Here an example, my Mail is a normal @rwe domain Mail Adress (no issues with other rwe Mails):
... },
"to": [
"kainico.horvath@rwe.com"
],
"subject": "Logstash CPU over 90% ALERT",
"body": {
"html": ""
}...

This is the given root cause:

"error": {
"root_cause": [
{
"type": "messaging_exception",
"reason": "failed to send email with subject [Logstash CPU over 90% ALERT] via account [work]"
}
],
"type": "messaging_exception",
"reason": "failed to send email with subject [Logstash CPU over 90% ALERT] 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 kainico.horvath@rwe.com: Recipient address rejected: Access denied\n"
}

My Mail is also Whitelisted.
Has anyone ever witnessed a similar problem and/or has an idea what the problem could be?

Many thanks in advance.

Kind Regards
Kai Horvath

@kainico this is an error that is being returned by your SMTP server. If some e-mails are being delivered but not others, it's likely being returned from a relaying SMTP server.
