[Spacewalk-list] Mail Notifications

Fri May 3 14:58:48 UTC 2019

Think this could have been (very) summarised as.....

"If Spacewalk notification emails are appearing from dev-null at localhost.domain (and therefore queueing) and you would like the address to be a valid one for your organization, include the web.default_mail_from variable and appropriate value in /etc/rhn/rhn.conf"

Now done that and waiting to see if future notifications get through to me.

Regards
Phil

The dev-null address is the default:

web.default_mail_from = Spacewalk <dev-null at localhost>

What exactly is "no difference"? You don't write your exact configuration but only write about "default_mail_from" and not "web.default_mail_from". Thus:

Does it still use the dev-null address as from address

or

does it use the correct from address you have set but it's still not working?

Are you sure you have set the correct variable "web.default_mail_from"?

Well, sending mails with "localhost" as sender domain is generally not a good idea, unless it all stays local anyway...
