Set graylog FQDN for SMTP Gateway

Graylog Central (peer support)
1

Hi,

i’m new with graylog and i playing with mail alert. But my smtp gateway does not let graylog send mail, because it does not send “HELO FQDN”.

I did not find where to setup my FQDN in graylog configuration. Someone can help me?

Thank you for help.

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?

did you use the OVA or did you install Graylog yourself?

No i setup graylog on a centos server.

you should check the configuration section @jochen has mentioned already:

If you had set everything matching your local settings.

hi finally i found a settings which work :

transport_email_hostname = localhost

rather than

transport_email_hostname = my_gateway

thanks for help.
