this come in a "failure notice" email from qmail,
but when checking with spamcop - the IP is not actually in their black list.
very strange, but i have it dozen of bounce-backs last week from the issue, and my client are complaining that their mails are not getting received, so there must be an issue somewhere.
anyone else getting these too? seems to be on win6 and win12.
thanks
