As the thread name says, what do you think of greylisting.org? In what ways/directions should I develop it?

I do not send bulk email or spam email. I probably send out less than 5 email messages a day. Yet, when I tried to respond to a client who requested a quote, my messages were greylisted and didn't get through. I didn't notice this until over 24 hours later, and by then I lost the opportunity to bid on those jobs. So for me, greylisting has probably already cost me $5000 in work. Thanks a lot.

Hi guest,

First of all, greylisting is not anything that I thought up. All I do is run this website. I also have no affilitation with any of the various greylisting implementations.

Regarding your problem, it's a bit difficult to say exactly why your email apparently got bounced with such a message (I'm currently trying to brain storm for a page/FAQ to answer that exact problem).

What email program/server do you use?

Hello bjarne,

First of all: thanks a lot for http://www.greylisting.org. I finally found an answer, why several mails we sent the last weeks didn't reach their recipient.

This doesn't mean that I'm glad about greylisting at all. Some of our mails were returned about ONE WEEK later - much too late in our daily business. The comments of "send mail again in 500 seconds" raise anger if you get this comment 500.000 seconds too late. But this is beyond your responsibility i think.

greetings from germany ;o)

Hi.

I work for a tour operator based in Oslo and i want to thank you for doubbeling my work load. Not only do I get to send all my offshore e-mail twice, I get to stay overtime and make sure that critical e-mails get to their destination every damn day! The problem with, excuse the term, people like you (i.e "techies") is that you don't understand that telling someone the technical reason that their critical e-mail didn't get through, with a lot of techincal talk, does not change the fact that they have to do the work that was supposed to be done, all over again and on top now have to explain to directing managers that because of some "trekkies" with illusions of grandure on the internet, he didn't get the rather critical email regarding one of the clients alergies, and because of this the client spent his holliday in the hospital, and blames the hotel, tour operator, and everyone else.... exept graylist.org. Because they just want to make the world safe from spam.....! Perspective is NOT an option, it's a pre requisit for doing you damn job!

Actually i think the site and the concept is great. I run 500 domains for clients and the tradeoff between ( initial only) delays and reducing spam by 50-100% is awesome..

One thing that is important to maybe mention on the site is that any greylist implementation must be accompanied by an explanation to email users as to whats happening and why its happening...

interesting. this seems like a troll or maybe even an astroturfing spammer.

greylisting does NOT require manual intervention by users. the MTA (sorry to talk technial on a technical site -- MTA is the mail software that handles transfering e-mail around -- stands for mail transport agent) involved will automatically resend the message. unless you are running or your ISP are running for you a broken MTA (in which case you will have more problems that with just greylisting a lot of e-mail sending won't work for you) as an end user you won't notice greylisting at all.

Since you are so confident in this "ultimate spamblocker" why don't you come down here and have a look. Here, atleast, it doesn't work like you intended. I dont care what the techical specs of sendmail says. Why it doens't work is not interesting to me, what is however is that this "feature" has been implemented without telling the people who use this system day in and day out about it. So when it fails, as it does in our case, it causes a lot of frustration and extra work. Why should it be my concern what kind of mailservers my ISP runs? Don't I have enough work already?

And no, this is not a techical website. It's the _only_ website with any kind of feedback regarding this system, as far as I know, wich puts it in the public feedback category.

I think if you're stupid, life is going to be painful. There's no real way around it.

I agree and I think if you had the perspective you require in other people, you wouldn't have written your troll.

Doesn't it make you frustrated when other people know more than you? Doesn't it seem like figuring out the problem would be a better idea than ignoring it and blaming it on people who know things you don't?

Just so I'm not only feeding the troll - I think this site is a great resource for anyone thinking about greylisting. Whether its a public forum or not has nothing to do with whether technical information is appropriate - it is. If you don't understand.... Look It Up.

I think you should moderate your forums, you have a fledgeling site - which could become a great resource.

I personally have reduced the level of spam on all sites i manage by about 90% and above by installing greylists, reducing CPU intensive scanning as the botnets are just not interested in waiting.

I personally found your site interesting and useful and am including it in any mail i send out to prospective clients as a way of explaining what greylisting is.

We will be requesting to link to you from our resources pages after our current re-design.
