I’m not an evangelist, so don’t please don’t misinterpret. I don’t really care for it. I help run two small companies; one of them is a tech services company, the other is a hosting services company that supports the other. The tech/sales side of the house has been using Sendio for 5-6 years. They have a local appliance. Sending outbound mail to a recipient adds addresses to the auth list automatically, and they have a web interface that they can review from time to time to add people / lists / welcome spam as they please. They find it all quite manageable, and by the nature of the product, neer ever see a single piece of spam.
They also mention it in client meetings, or the client is exposed to it and asks about it, and that’s part of what gets the clients curious. I can’t change what makes them happy, I have brought up these points before, but they’re really please with it. So I have to deal with it. Which is why I’m asking questions. Our customers are all SMBs. I have to run my spam filtering a little loose because sales-related mail often smells a little spammy to begin with, and my clients work with people world-wide. I do have a little trouble from time to time with the poor reputation of countries in the medditeranean, south america, asia, etc. I have an alligate on the front end, declude and message sniffer on the backend. Thanks for your feedback, all of you. It’s very welcome and informative. I’m always trying to think of ways to make things better.

Challenge/Response systems are seriously flawed. Reasons include: [1] You end up being a spammer (the majority of spam sent to you will result in confirmation requests being sent to innocent victims) [2] Spammers now send pretend confirmation requests, presumably to make people less likely to respond to C/R requests [3] Many people respond to C/R requests that they never initiated (so you could still get spam or viruses). A number of people in the anti-spam community have said that they always respond to challenges, whether or not they initiated the E-mail. [4] C/R companies have been known to send out spam and harvest addresses of people sending to their customers, and apparently sell those addresses to spammers [5] The C/R system is patented, so most anti-spam programs using C/R have legal liabilities waiting to be ironed out [6] Confirmations sent to mailing lists won't work [7] Confirmations sent to others using C/R won't work (they send you an E-mail, your C/R system challenges them, but their C/R system challenges you, yours then challenges them, etc.). [8] People that offer a free service end up losing money (by spending time investigating and responding to C/R systems, dealing with spam received as a result, etc.) and sometimes get fed up with C/R systems and eventually stop offering free advice (never knowing how many people won't get the advice), harming everybody. [9] Legitimate E-mail from automated services won't be seen (such as when ordering products online) David Barker Mail’s Best Friend Email : [email protected] Web : www.mailsbestfriend.com <http://www.mailsbestfriend.com/> Office : 1.866.919.2075 cid:[email protected] From: [email protected] [mailto:[email protected]] On Behalf Of Michael Cummins Sent: Thursday, June 13, 2013 8:08 AM To: [email protected] Subject: [MBF]Re: Fighting the good fight! My clients are very interested in Sender Verification services. One of them has a Sendio Appliance, an expensive solution. http://www.sendio.com/platforms/appliance/ Anyone know, in this post-declude world, how we could accomplish something like that? Sender sends mail ; sender verification sends them an e-mail, letting them know that they need to reply in order to be on the approved senders list. After that, it’s never blocked again. Would love to hear anyone’s thoughts on the matter. - Michael Cummins
