20.33.0.0 - 20.128.255.255 is Microsoft but SpamCop reports 20.73.0.72 directly to the spammer. I've seen similar misreporting for other Microsoft-hosted spammers.
 
 

Routing details for 20.73.0.72
[refresh/show] Cached whois for 20.73.0.72 : abuse@microsoft.com
Using best contacts abuse@microsoft.com
Using rdns to route to correct Microsoft department
host 20.73.0.72 = vi44.viv0digital.com. (cached)
abuse net viv0digital.com = postmaster@viv0digital.com

In this case, the spammer is sending "invoice reminders" purporting to be from Brazilian carrier Vivo with "download/print" link that redirects to a java scri_pt-wrapped malware download.
