I have a list of about 2000 email and i am looking for a way to sent them with a bulk email software. I have a dynamic ip from my isp and for now i use the bat software. when i try to sent the software stops and reports that i am blacklisted in spamhaus.

IN the past i had a static ip and i was using smtp private software and i was able to sent without problems..

Do you have a good guideline so i could sent the emails without most of them to return back to me?
