Domain policies + Deny + Open Rates


I need a little help on a particular scenario. My main question is -- will the blocked emails (via domain policies deny domain) cause a negative effect on my Open Rate? Meaning it will be counted as unable to send?
1. I have an existing campaign that is already sending
2. I paused the campaign
3. I changed the delivery server to deny hotmail and laposte
4. I resumed the campaign

Thanks a lot in advance!
It should not, the domains will simply be skipped by the delivery server having the policies, so the emails will not be sent in the hope another server can pick them up and send them, a server which is allowed to do this.
