Please share your ideas Edit I want to make this question more clear Registr...
Hi we have just noticed a bunch of Nigerian spam accounts in our email system. Now, we do have a reCaptcha in the signup form but apparently they circumvent it, manually or otherwise. It seems like a semi-manual circumvention since the accounts aren't created in bulk but instead as a steady stream with a few minutes in between. Since mo...
I want to query Spamhaus's SBL using a domain name. I know this is possible to do because this form (Find SBL Listings by ISP Domain Name) does it and SpamAssassin does it, but I can only seem to get it to work with IP addresses. I took a quick look at the SpamAssassin code, but it has been so generalized that I could probably spend a ...

[Our website] is very dependent on being able to successfully send email to its members. We are currently having trouble reaching all our members, especially hotmail users. What do you recommend we do to improve our sending of email? We are sending heavily user customized emails. So a third party solution would need a good api to sup...
There is a growing trend to use port 587 for all client to MTA communications. It's in a standards track RFC: http://www.ietf.org/rfc/rfc2476.txt My question is "Why?". Why have 2 instances of a SMTP server running on the same server, if they both do the same thing? What security feature does it provide, besides giving me 2 things to...
I've been getting very annoyed at this as no matter what it seems spam filters are still calling my websites auto responder as spam. I've set all my headers correctly and this is what I have so far! $headers = "From: Name<[email protected]>\r\n" ."Return-Path: Name<[email protected]>\r\n" ."Reply-To: Name<[email protected]>...
I've just noticed a domain of mine has been blacklisted by backscatterer.org. Time to investigate. When you go here: http://www.backscatterer.org/index.php?target=backscatter it describes the behaviour it wants to dictate, and because google, yahoo, and others are blacklisting domains blacklisted by this group, this pretty much dictat...
I'm trying to send emails from my Ruby on Rails application, and whenever I use the following format: Jon Doe <[email protected]>, Hotmail marks the email as spam. However, when I use [email protected] without the name, it goes through fine. Anybody know how to get around this so my emails don't get sent to spam for hotmail users? I h...
PHP's mail() function sends mail fine, but Swiftmailer's Swift_MailTransport doesn't work! This works: mail('[email protected]', 'test '.date('H:i:s'), ''); But this does not: $transport = Swift_MailTransport::newInstance(''); $mailer = Swift_Mailer::newInstance($transport); $message = Swift_Message::newInstance('test '.date('H:i:s')...
Let say I have a website that allows users to send articles on that website to a friend. The way it works is that when the "send to a friend" link is clicked a form appears and it allows users to fill in the details and an email is sent to their friend. The user can put in a "from" email address and a "to" email address into this form ...
Hi, I'm working on a project where I need to create a spam database and accept submissions from users. Accepting the submissions is easy, but I was trying to figure out how to weight these submissions. Let's say the database consists of words, and i get the following submissions: * 137x "banana" * 22x "apple" * 1x "exploding mouse" No...
This is the issue: Genuine spam will arrive, be scored appropriately, then the scored mail will be thrown into the notspam folder: Aug-26-10 04:33:11 Connected: x.x.x.x:35601 -> x.x.x.x:225 -> 127.0.0.1:25; Aug-26-10 04:33:11 93591-13575 [BombSubject] x.x.x.x <[email protected]> to: [email protected] [scoring:36] -- ...
When sending HTML e-mail, I understand that it's a best practice to send a plain text version as well. But my question is: Must you send a plain text version as well? What are the repercussions? ...
My Question: How does Outlook 2007 decide if it should redirect an e-mail to the Junk E-mail folder? Background Story: When I send a simple HTML e-mail from my domain mailbox, it's being redirected to the Junk E-mail folder.

For protecting my website from spam and malicious registrations/posts/etc, is it better to use something like reCAPTCHA or an anti-spam script? I was planning on implementing reCAPTCHA for user registrations on my site, using the CodeIgniter reCAPTCHA library (here). However, the CI forum on this library (here) has a lot of negative vi...

With honeypot, i mean more or less this practice: #Register form <style> .hideme{ display:none; visibility: hidden; } </style> <form action="register.php"> Your email: <input type="text" name="u-email" /> Choose a password: <input type="text" name="passwd" /> <div class="hideme"> Please, leave...
I want visitors to be able to click on (or copy) an email address directly on my webpage. However, if I could make it (a little bit) harder for bots and other crawlers to get said email address and register it in a spam list, it would be awesome. I found different ways of doing this (i.e. encoding mailto HTML links), either with JavaScr...

Are there any spam filters available for Django/Python? If not, what types of algorithms can be used for automatic spam filtering or flagging? On a more general note, does anyone k...
