mmm, interesting. So I take it that transport_email_use_ssl should be false and transport_email_use_tls = true should remain as is.
Good!
Now, after trying this configuration, I got one step closer to being able to send e-mails. I do however, have another error:
The Graylog server encountered an error while trying to send an email. This is the detailed error message: org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.office365.com:587 (com.sun.mail.smtp.SMTPSendFailedException: 550 5.7.60 SMTP; Client does not have permissions to send as this sender [DB7PR05MB4380.eurprd05.prod.outlook.com] )
Which is interesting. I take it that from this message and from this post, my correct setup should be:
# Email transport
transport_email_enabled = true
transport_email_hostname = smtp.office365.com
transport_email_port = 587
transport_email_use_auth = true
transport_email_use_tls = true
transport_email_use_ssl = false
transport_email_auth_username = noreply@company.me
transport_email_auth_password = noReplyPass
transport_email_subject_prefix = [graylog]
transport_email_from_email = noreply@company.me
I keep finding posts that give me the impression some field is not being properly set:
But It is still failing. Is there any other configuration setting I am missing in Graylog?
