Message has not been sent. Server reply - "JunkMail rejected.....16694 is in an RBL:"
Only one email address out of 7 gets this error message. I checked the IPs and domain names including ones from InMotion hosting email servers, and neither one is blacklisted as a spammer. If I choose a different email within the same domain that is being rejected, the emails being sent without a problem. Only one email address in a domain on the secure235.inmotionhosting.com server gets the spam rejection. Please advise.
