This error message is a dynamic block on our system. Dynamic blocks are placed on an IP address when the IP's statistics break our threshold. These are automated blocks that are removed by the system within 24 hours once the complaints are again
below the threshold.
What exactly are you eMailing AND how many eMails are you sending? It sounds like people are reporting it as SPAM and if too many people do so your IP becomes blocked. So until the complaints stop rolling in looks like you will be blocked.
