Blacklist not working on One particular email address

[Ned Boddie]

Hi all,

I've got MailScanner set up and working well except that one particular
email address added to the blacklist seems not to work at all, the email
address in question is:

owner-nolist-x at WWW-TOPSITES.COM

and a header sequence from an example email is as follows:

Return-Path: <owner-nolist-x*info**STUDIOFIVEARCH*-COM at WWW-TOPSITES.COM>

Normally I'd expect to see some indication that the blacklist had caught
this beast.

Can anyone shed some light on this issue for me, please?

TIA
