Gmail not being delivered

When sending group emails from gmail, I started received the message five days ago:

This is an automatically generated Delivery Status Notification

THIS IS A WARNING MESSAGE ONLY.

Delivery to the following recipient has been delayed:

     machouinard@cox.net

These only came for cox addresses; all the other emails went through. Two days ago, the message changed: (again, all other emails went through. Only Cox addresses were affected)

Delivery to the following recipient failed permanently:

I found this forum post, but I don't see a fix for it, although it occurred in August.

    There seems to be a tightening of the Spam filters in the last couple of days - you aren't the only one who is noticing this problem.  It does seem to be triggered on either group mails or those 'edge' cases for spam.

    Here's Cox's instructions for mis-identified spam: http://www.cox.com/residential/support/internet/article.cox?articleId=df249270-39d8-11e0-e473-000000000000

    Gmail--

    You are not alone. My wife and I, and several of our friends, have had messages to Cox subscribers bounce. Seems to occur especially from gmail senders. 

    A friend and I both called Cox support and were passed to Level 2. The tech I spoke to confirmed that Cox has recently "tightened security" on e-mail due to "SPAM bots coming from gmail servers." 

    He said "it's Google's responsibility." The only other suggestion he offered was that we should ask all our e-mail contacts (!!) (mostly not Cox customers, of course) to log in to postmaster.cox.net and request to be white-listed.  

    I told the tech this was a total non-starter. 

    I actually have some other e-mail accounts I can use for a while (gmail and a private domain) but my wife does not and she's pretty excited. It's very distressing to know that you're not getting messages but you don't know which ones are missing and there's no way to tell your correspondents what's going on. I expect we will drop Cox altogether if they don't undo this "security" measure within a few days. We already have a FIOS line for telephone service so the switch will be easy.

    I would have asked him to go there, because obviously they haven't. If they had, they would have seen:

    "Can I be whitelisted?

    Protection of our customers and network is paramount. Therefore, we do not whitelist."

    Anyone asking you to ask over a billion gmail users to white list themselves was a idiot. I don't care what tier they were in. 

    I suggest no longer using Cox email. IMO it isn't secure, dependable, or flexible. If anything, I would consider Cox.net domains as spam and not gmail. They have become the new Hotmail accounts, with more being used by spammers then actual users.
