Verizon's Aggressive New Spam Filter Causing Problems 311

aviancarrier writes "Verizon DSL has turned on a very aggressive spam filter that is blocking lots of long-time legitimate emails. Emails get bounced with an error: ' host[] said: 550 Email from your Email Service Provider is currently blocked by Verizon Online's anti-spam system. The email "sender" or Email Service Provider may visit and request removal of the block.' That whitelist web page lets you request one address at a time to be whitelisted with no guarantee for their response time to process it. I have tested multiple email sources and only one got through. As a VZ customer, I just spent 28 minutes on a call to tech support, eventually got a supervisor who knows nothing about the new spam feature, and would only agree to email a manager who doesn't work weekends about it. I warned her that VZ has a public relations problem but she was too clueless to understand." Many users have submitted this problem so it seems to be a pretty far reaching problem. There is also a discussion going on over at Google about this problem.

I do admin my own domains but keep my at&t for special purposes. It is possible to filter over 99% of spam through a combination of techniques.
      • Yeah, this system from Verizon is junk. It blocks legitimate email constantly. We currently have 2 businesses in the same building. For some reason, Verizon is constantly blocking one of our business domains from the other business domain. And no amount of phone calls or emails or removal requests have done anything for us. We will shortly be moving to a new provider.

        [Full disclosure for the following comment -- I program voice response systems for a living. However, I only implement what they force me to, and sometimes that sucks.]

        From that page:

        We will soon publish a list of the best and worst mass-market consumer companies in the US based on how long it takes to get to a human on the phone and on the quality of support received.

        That's very nice, but it doesn't seem like a very intelligent way to measure customer service. As a trivial example, suppose you want to know your credit card balance. A decently programmed voice response system can give you that information quickly and clearly, and in much less time than it would take to get the same data from a human. If you're lucky, the IVR won't even try to sell you something that you don't need.

        Yes, I know that there are times when the available pre-programmed options are not useful and speaking to a representative is the only option. But do you want to have to wait in queue for an agent who has to handle ninety-twelve "what is my balance?" calls before it's your turn? Now ask yourself why the call centers are being outsourced to overseas providers ...

        This "I only will deal with a human" attitude is pointless. Better to demand that corporations fix their IVR systems, because they're not going away. (And maybe I'll get hired to write more VUI specs instead of having to implement what 'the business' thinks it wants.)

Sure, it's 60% more expensive, but in exchange you get no PPPoE, static IPs, no silly blocked ports or server restrictions, and intelligent tech support that answers the phone quickly.

    I ran a bulk-sending system (legitimate!) to email Frontier Airline's frequent flyer members, and Verizon was the biggest single problem getting mail through. I don't think I ever did get them to accept our runs at all.

    The big thing they already had in place was that they want to connect back on port 25 to the sending system AND make sure it responds initially with the same name it's using to send mail out. Not a bad thing overall, I suppose, but I can see how it would block quite a few messages from providers that use separate sending servers from their receiving servers. I finally had to set up SMTPFWDD on both outgoing servers to accept connections and silently drop any emails they get, that helped, but I think they still rate-limited heavily.

    I'd say if you depend on getting your email, Verizon's not a good ISP to use.

    "I warned [a tech support supervisor] that VZ has a public relations problem but she was too clueless to understand."

    Having worked in tech support for a large company, I can assure you that the position of supervisor for a tech support call centre really doesn't have nearly as much influence on coprorate public relations as you seem to think that it has.

    Most of the people in her position would be surprised to find out that any one from the head office even knows that they exist, let alone cares about what they do or asks their opinion on issues like PR. It's normal to be annoyed when a company like Verizon screws up like this, but lashing out at the tech support staff just because they're the easist people to reach really doesn't help anybody.

    • Having many friends who work in call centers for "tech support", they tell me this supposed "supervisor" is actually just the person sitting next to them.
    • Thats just another way of saying "I'm no good at my job". Whether you feel appreciated by your corporate overlords or not, you're a customer facing part of the company and you are therefore every bit as important to PR as sales. Even more so in a large way - anyone calling tech support *already has a problem* and your attitude and ability to solve that problem are a *huge* PR influence.

Sure, you could start a 'PR Nightmare' in a low-paying customer-facing position, but you're not empowered in the slightest to actually solve them.

    Perhaps she was too jaded from hearing customers complain that Verizon has a PR problem.

    "We don't care. We don't have to. We're the Phone Company."

    From what I've heard (and what I experienced from having their service in the second half of 2000), this is nothing new for Verizon. They're only interested in the money-making aspects of the telecom business, and drag their feet on everything else. The setup of this aggressive new spam filter was probably one of those "money-making" items, since it means far less spam traffic and decreased accusations of hosting spam bots. Of course, when customers start complaining that they can't send email to specific addresses, they have to deal with Verizon's understaffed, undercapable customer service departments, who will most likely be faced with fierce opposition from the suits in opposing the "grand money-saving, liability-reducing spam filter".

    Also, keep in mind that when Verizon acquired MCI, they acquired UUNet, a tier-1 ISP with some serious spam problems of their own []. I wouldn't be surprised if taking on UUNet's elephant-on-their-back was part of the rationale behind the new spam filtering policies.

    My company implemented my blocking methods [] and saw an instant reduction in spam from a deluge to a tiny trickle. The three most effective filters are:

    1. Requiring HELO,
    2. Rejecting non-FQDN HELO strings ("" will get you in, but "myleetmailserver" won't), and
    3. Rejecting HELO strings that blatantly lie (you're not "localhost" or my public IP address, no matter how many times you ask).

    More and more ISPs are starting to implement the same compliance checks. Would any of these reject your system's mail? Several of our customers had misconfigured outbound servers and we helped them fix their systems. We were only early adopters, though; if we hadn't caught the problem then a major ISP or five would have started rejecting their email without being so helpful.

    Maybe VZ is in the right this time. Are you sure they're not?
