Re: [Spacewalk-list] Mail Notifications
Think this could have been (very) summarised as. "If Spacewalk notification emails are appearing from dev-null@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.

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?

Re: [Spacewalk-list] Mail Notifications
Hi Graeme Thanks for your response. If I send a test email the from address is root@hostname.domain<mailto:root@hostname.domain> and these appear in my inbox immediately. The from address for the notification emails is dev-null@localhost.domain<mailto:dev-null@localhost.domain> and these just queue up. I’ve tried setting the default_mail_from to either of the 2 from addresses, and re-started Spacewalk services, but it makes no difference. However, I’ll check with owners of mail relay, as has been suggested separately.

First place to look is into the mail logs on your relay and find out what problem it is. Until you know the problem it's pretty pointless to guess what it might be and what might fix the problem. Is there some Spacewalk configuration that needs to be done to enable it to utilise Postfix perhaps? As an example I’ve seen some references to *web.default_mail_from*, in */etc/rhn/rhn.conf*, but I’m not sure what it actually needs to be set to. You should know what your mail relay needs to process the email. So you should know what you need to set. So find out what the problem is on your mail relay and then you most likely know what's wrong or missing. Then you have to either fix your relay or spacewalk or both, depending on what it is...

Re: [Spacewalk-list] Mail Notifications
The error message you detail looks to me very much like an Exim response, not Postfix; your system looks to be accepting the locally-generated mail but the mail relay is struggling with it. If you’re not sending from a fully-qualified, verifiable sender address within your own institution’s email namespace(s) then you might well find the relay won’t accept the messages – although the 451 error implies that there’s something the relay can’t process rather than something it rejects on.
