[Spacewalk-list] Email notifications - mail_from not working

[Ricardo Esteves]

Hi,

I've configured this setting on /etc/rhn/rhn.conf:

web.default_mail_from = spacewalk at domain.com

and restarted spacewalk services, but spacewalk is still sending as 
<dev-null at localhost.domain.com>.

Anyone knows how can i find why is spacewalk not assuming the configuration?

CentOS 7 (x86_64)
Spacewalk 2.3

Best regards,
Ricardo Esteves.
