Rejected messages
It appears the new spam filtering service Cox is using (cloudfilter.net) is blocking a lot of valid mail. I would like to know where our individual portals and addressbooks are that we can configure our own whitelists and to be able to see what messages are being rejected. It is one thing to be identify a message as spam, and another thing entirely to reject them without notification. I have mail senders from a good number of places and since my mail volume has dropped by over 75%, it is quite safe to assume the spam aggressiveness thresholds are set quite high as well as are the bulk sender identifiers and anti-spoofing features. While you claim to not whitelist senders, you do need to provide your users the ability to do so. No doing so means you are censoring email Also, it is poor form to put a like to review changes and then have it error out. http://postmaster.cox.net/confluence/display/postmaster/Error+Codes If you are going to implement such a service you should become a lot more responsive with corrective actions. I am now on my second day waiting for an answer on my ticket with Tier 2, and third day with the actual issue at large.
Cox email censorship?
I've been trying to send an email from my Cox account to another Cox account and when I do, I get: An error occurred while sending mail. The mail server responded: <xxxxxxxxx@cox.net> message rejected. Refer to Error Codes section at www.cox.com/.../email-error-codes.html for more information. AUP#CXSNDR. Please check the message and try again. The email is long and has the following link in it to a government website: https://www.azleg.gov/FormatDocument.asp?inDoc=/ars/33/01804.htm&Title=33&DocType=ARS When I remove the link, the email goes through just fine. If I send a short sentence with this link, it goes through just fine. But long text with this email and I get the error. When I call support, they tell me that I need to spend $10/ month on a support plan and they will help "fix" my Thunderbird email client. Rep says that if the problem ends up being on Cox's end that they will not give me a refund. Is this a ploy to make more money from us? I am baffled why this would be a problem on my end. Also today I tried to respond to a perfectly valid commercial email message today and same error message. I have not played around with removing content, but this is unacceptable.
