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...

Cheers,
