I think you are thinking it as only a DNS issue. But creating a sub-domain, means that the from needs to match too, therefore you may need to remap all your corporate email addresses from j...@iecc.com to j...@corp.ieec.com to separate from the emails sent by your application at iecc.com (if you want to keep the first party signing)
I'm not sure that many email admins like to play with MS-Exchange and their boss email address...

If there is a reason why people aren't able to use a d= domain per stream, I wish someone would explain in simple terms that even a dimwit like me can understand. The only arguments I'm aware of is that hostile or incompetent DNS managers refuse to install key records, which isn't a very good reason to add cruft to a standard and "I want to do it some other way" which is even worse.
