で、DSBLのデータベースに載った場合にしたがって解除要請したのですが、
abuseではなくpostmasterに送ってしまいました

ttp://dsbl.org/listing
で確認しても、History 項目に"Removal Confirmation Sent:"が見当たりません。
abuseに送り直そうとしても、

Please confirm that:
　1.You are an administrator for the IP address 60.35.211.12.
　2.You have investigated and solved the problem that caused your listing.
　3.You have tested that you can receive mail at abuse@plala.or.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.

こういう場合はどう処置したらよいのでしょうか。
