DSBL: Send Removal Confirmation
Please confirm that:
You are an administrator for the IP address 133.205.47.185.
You have investigated and solved the problem that caused your listing.
You have tested that you can receive mail at abuse@mesh.ad.jp from the outside world.
If you have not met these requirements, do not continue: DSBL only sends one removal confirmation
per-IP every 7 days. Sending one to an address that does not work will introduce delays in your delisting.
Removing an address that is not fixed is likely to result in near-immediate relisting as spam begins to
flow to testers from your IP again.
