Spam

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.

    There are different things that may trigger the spam filter, sometimes having a large number of recipients and a combination of using the Bcc: field may cause it to think it is spam. I'd recommend trying to send to 10 at a time first, then if you do not get any errors gradually increase the number.

    I send emails via BCC to a list of 55 several times a week for the at least the last 5 yrs.  2 days ago, I started getting the same spam message and my email is not sent.  I then broke it up into several emails with only 10 BCC receipents.  All the emails went through.  So what have you all changed and can you please change it back so I can send my mails to my friends?

    Thanks John

    To my knowledge, there were no changes to the mail server. There are just some things that may trigger the spam filter and reducing the number of the recipients seems to have allowed the messages to go through.
