On the SpamCopBL list and Not on the SpamCopBL list at the same time?

There are several possible reasons why an IP address may seem to be both listed and not listed at the same time.

1. Not all users of the SpamCop BL are using real time versions. Some use cached versions that may take some time to update, so even it an IP address shows as not listed in the real time list, it may still appear in some of the cached lists that have not been updated.
2. Some mail rejectors use standardized replies that are not always accurate. They may state that a message was blocked due to the SpamCop BL when in reality it was blocked for some other reason.
3. The IP address may have been on the SpamCop BL at the time when the message was bounced, but had been removed prior to the sender checking the list.
