I continually get spammed from this location in London.

Unsubscribe doesn't work. Every spam has a different return email address, except if your read down the the information in "View Source", there is an address that is consistent in all of the spam.
Message-id: <0MR700IP03Z0C650@vms172091.mailsrvcs.net>
I've entered "@vms172091.mailsrvcs.net " into email spam blocker but it does not block the spam.
How can I block all messages " @vms172091.mailsrvcs.net " ?
I've reported every one of these to " spamdetector.notcaught@verizon.net ", and have tagged each for Spam Detector folder but no action is taken.
What can Verizon do to block this source?
Where can I report an international spammer not complying with US anti-spam law?
