I guess the Guarddog was sleeping, or chewing on a bone, because a few emails from domains and addresses I have blacklisted are still coming through. I blacklisted On-One Softwares domain name (Good software, but they send a LOT of emails once you download a trial), and after receiving another email from them a few days later, I black listed the actual address the email come from. But alas, they are still coming through. I got two more from them today. There have been another few domains that sneak past the Guarddog, but On-One is the main offender. I will start tracking them no as well.
I have forwarded the messages to MXGuarddog, so we’ll wait and see if they respond.
