Good day dear Graylog community, I hope you’re having a good day.
I have an issue, I’m trying to configure a SMTP server but the enterprise SMTP server is working with STARTTLS and after graylog.conf configuration, the connection is unsuccessful:
Sending test alert notification failed with message: Sending the email to the following server failed : smtpservercompany:25
The graylog.conf is the next:
transport_email_enabled = true
transport_email_hostname = smtpservercompany
transport_email_port = 25
transport_email_use_auth = true
transport_email_use_tls = true
transport_email_use_ssl = true
transport_email_auth_username = domainuser
transport_email_auth_password = password
transport_email_subject_prefix = [graylog]
transport_email_from_email = email@example.com
I can say that the authentication based on the domain user is working because I used Febooti (Tools -> Options… ->Email Server) and after the test I received the test mail, so no problem with user or domain.
I don´t know if there is a special configuration into Graylog in order to configure STARTTLS, this is my doubt, how can I configure Graylog for this purpose? I have tried different options (transport_email_use_ssl = false, installing sendmail locally) but no results.
I have to say that I downloaded virtual machine in OVA format.
Best regards and thanks in advance!
