I occasionally have emails I send to a number of recipients bounce back and not delivered -- with every email address I'd sent the email to in the body of the email, followed by the explanation/reason "552 5.2.0 WS181u0061B9AiG01S18lu This message was undeliverable. This message has been found to be a potential spam message, and has therefore been blocked. Please visit http://ww2.cox.com/coxagainstspam for more information." Visiting "http://ww2.cox.com/coxagainstspam" has provided no explanation -- and Cox's support reps won't explain the reason, either. So I'm between a rock and a hard place -- trying to send emails (to fewer than 100 email addresses at a time -- in the BCC field -- and I've reduced the number of recipients to as few as 50 and still had this happen [although not all the time], sometimes having them rejected as spam, but unable to find out what's causing them to be treated as spam so that I can correct what I'm doing that cause the assumption that they're spam. Cox's refusal to tell me what the rules are while punishing me for breaking their rules is like driving thru a town with no posted speed limit and getting ticketed for speeding. ANY help would be appreciated! Thanks.
