I have MaxBulk Mailer installed on a VPS and I plan to send a test mail to my +1 mil email list in order to remove bounces. I am looking for a cheap SMTP solution just for this operation. As you probably know MaxBulk Mailer does not have any features to rotate SMTPs as I would have used gmail/yahoo/hotmail accounts for this. I am opened for any suggestions you may have. Thanks!
