RE: Website link for 207.173.187.220

I guess I'll just have to wait the 7 days then start this process all over again and try to keep better track.  I have checked all my logs, message tracking, and my special email account (where all spam-marked email goes to) and cannot find any reference to any message sent by @dsbl.org.

I suspected it, and my question was rhetoric. You definitely should be 
able to find 2006/Nov/29 16:23:21 UTC (note timezone!) in your logs and 
look through all nearby events.

I believe, the magic word is "logging". Those damned computers do many 
things too quickly for a human eye, but every important events must be 
logged. It is not a law requirement, it is a "Good Internet Practice" 
:-). A condition for survival.

I trust you that your system delivers SOME mail to Postmaster. But we 
see also that some other mail is accepted and lost. Does it mean that 
your system operates in non-deterministic way?

Yes. I has been working as an ISP security officer, and I used DSBL 
delisting procedure nearly daily for my clients. It works as described.

So, now you know about a major bug in your system. Please read also
