Make sure you are sending with SMTP Authentication turned on. See Email Settings to correctly configure your account.
If your domain's SMTP settings do not work for you, it's possible your ISP is blocking common mail ports which are used to send email. In this case, you can use securemail.72mm.com via SSL (see Email Settings to correctly configure your account) or use your ISP's SMTP server for sending mail.
Spammers often send email setting the To and From headers as the same address (yours). The message you are seeing is what is normally bounced back to the spammer that sent the email letting them know it was blocked, but since your email address was forged as the From address, it's bouncing back to you. These messages are safe to ignore provided they are coming from our spam filter.
