Our company does work environment surveys, and these surveys are filled in online. All participants are sent a link to their survey in an email (personal code included). Some of our clients have employee counts in the hundreds and sometimes in the thousands. Our current solution is just using our SMTP-server to send this, without any form of throttling (VB6, CDO). (All recipients are usually "inside" the same domain, recipient@client.com) This is not a good solution, as you may imagine, this triggers every anti-spam/firewall/gatekeeper event in the clients environment. We are put in contact

There are a lot of captchas plugins in Rails and also many types of solutions for preventing spamming and flooding. So it isn't only Rails question. Let's see what types of plugins do we have: 1. Classic image captcha ( zendesk's Captcha , Simple_captcha, Validates_captcha, winton's Captcha , Raptcha). positive: Can be effective to prevent automatic decrypt (not sure about Simple_captcha, but it seems that both zendesk's and winton's captchas don't achieve that, as they use pre-generated images (instead of on-demand), so our possible spam bots can be learned on that images). negative: Require

I'm trying to email new registered users for email verification (PHP) but i don't get it, why would an email be sent to SPAM, i already checked out similar questions and all answers are about Headers, It seems a bit complicated for me to get known to those headers and how are they being verified, By sender website ? lets say i sent as user@google.com and the actual server domain is domain.com, how would it know? and is it one of the main reasons why it goes to spam ? I am using VPS, does it has anything to do with it ? I'm just trying to understand the clear/simple reasons of why would an

I'm using PHP Swift_mailer library to send emails to my customers' clients from behalf of customers. I use their SMTP server, port, login, pass: $transport = Swift_SmtpTransport::newInstance($mail_server['host'], $mail_server['port']); $transport->setUsername($mail_server['username']) ->setPassword($mail_server['password']); It worked pretty well for a few months, but now the emails started to appear in a Spam folder for some of my customers? Is it possible that the reason could be at my end (PHP server) or the problem in in my customer's SMTP server? Thanks in advance! It's because of your

When replying to a post (for example on Craiglist) that asks for sample code, is there a way to be (reasonably) sure of delivery? Here's the problem, stated as possible options and the negative outcomes: Link to the source code on an external site. In this case, there's a spam score metric based on number of external links that you could hit. Often your signature might contain a link. Attach it in a zip. Zip files are often considered in spam metrics and in some cases are just outright removed. This also creates an extra step for the recipient which isn't much but has to be multiplied by the

I'm seeing thousands of referrals coming from Russia and China every month from the domains below, I've tried adding the code below to my .htaccess file, and then testing it from another domain I own, but I don't appear to be getting the 403 Forbidden message I'm expecting to get. What am I missing? RewriteCond %{HTTP_REFERER} ^(www\.)?([a-z0-9-]+)\.social-buttons\.com$ [NC] RewriteCond %{HTTP_REFERER} social-buttons\.com [NC] RewriteCond %{HTTP_REFERER} googlsucks\.com [NC] RewriteCond %{HTTP_REFERER} 4webmasters\.org [NC] RewriteCond %{HTTP_REFERER} aliexpress\.com [NC] RewriteCond %{HTTP

I'm making a simple PHP mail sender to send an image to multiple addresses at a time. Don't know why, but the emails keep on arriving at the SPAM folder, no matter what email manager I send them... Here's how I call the PHP mail sender file: $.ajax({ url: 'mail_sender.php?receiver=' + receiver + '&=lang' + lang, success: function (response) { console.log('Mails ' + response); } }); And this is my PHP file structure: <?php // Reciever $_to = $_GET["receiver"]; $_lang = $_GET["lang"]; // subject $subject = 'My Subject'; // sender $sender = "sender@sender.es"; // message $message = ' <!DOCTYPE
