Hi thank you jochen,
i’ve already read this documentations, perhaps i’m missing something, but never find where to configure the fqdn of my server.
Here is my log :
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 : my_smtp_gateway:25 (javax.mail.SendFailedException: Invalid Addresses; nested exception is: com.sun.mail.smtp.SMTPAddressFailedException: 504 5.5.2 <my_server>: Helo command rejected: need fully-qualified hostname )
Graylog juste present himself with hostname (my_server) and not fqdn (my_server.domain.tld)
Do you have an idea?
