  Hi,
  I'm interested in your script, please try to answer this, Thank you.
  I'm confused with this parameter "smtp_check": false/true
  can you explain when will this be true and when will it be false?
  I tried to check this email "[email protected]" with this email as verifier email '[email protected]', and got "smtp_check": false,
  shouldn't it be true,? as both email exists...please explain.

  Hi koromanoj,
  
  I'm sorry for late reply because of Codester is down yesterday
  
  Regarding your question, the "smtp_check" parameter is to determine that the checked email is exsit or not. Technically, our script will open telnet connection and send HELO command to ping/pong with email server. However, in some case, for security reason - email server will block all HELO command to protect their email accounts, "hide" them from outside => This is a reason why some case the checked email is real & exist but our script still show as smtp: false
  
  Best regards

  Hi, While going through the demo i find following as requirement, I will be buying, but want to know if you shall be going to implement these in future upgrades.
  1. Background scheduler, instead keeping it on browser.
  2. Authentication, the script should be behind the doors.
  3. Proxy Support, as major ESP block if tracks tons of helo request from single ip.

  Hi Eyugcom,
  
  This is just a simple script for verifying email so it does not has advanced features. I added some more features then the script’s pricing have to be increased too regarding Codester’s rule
  
  So for recent plan, I still keep it simple as it should be but for your requirement, it still be easy to implement, especially with PHP cli

  Hi @fernanm,
  
  This script just requires hosting with PHP 7+ with port 25/465/587 is opened.
  
  I personally prefer DigitalOcean/Vultr/Linode as VPS provider or Bluehost/Siteground/Hostinger as hosting provider

  Hi Spanish206,
  
  Thanks for your comment. Do you need export/filter function for bulk email verification?
  
  This item is only a script for verifying email then it does not have full features as an email platform. But thanks for your suggestion, I will add this feature in the near future.

  Hello,
  
  I am interested in your email verification script but I have a few questions about your product.
  
  1. Can your script verify millions of emails?
  2. Can it work all the times and keep verifying emails on auto mode?
  3. Can we add multiple servers to avoid IP black list?
  4. How accurately it verifies the email list?
  5. Can it import and export excel columns (name, phone etc...)
  6. Is it slow or fast?
  7. Can you help setup everything?
  
  Looking forward for your reply
  
  Thank you

  Hi Faiz,
  
  This is just a PHP class for verify email so if you need to verfiy milions of emails, you should have a good architect (queue)/server to run it.
  
  1. Yes, you can but you have setup queue/node server to check. Let's say you have 1M emails, average time to verify an email is 10 seconds (depends on target server) then you will need 1M x 10 seconds = 10M seconds ~ 2777 hours . But if you have 1000 workers to run parallel, you will only need 2.7 hours. You can use AWS lambda function to scale your worker quickly.
  
  Please note that, you can run this script from command line, each command can be an instance so 1000 workers here may not are 1000 servers. It can be 10 server with 100 tasks run on it
  2. Can it work all the times and keep verifying emails on auto mode? => I cannot get your idea but if you want to track an email, you should have a schedule task to verify email
  3. Yes, you can see my answer from #1
  4. It depends on the target server emailconfiguration.
  - If they block all incoming requests for checking email, we cannot determine the email exist or not
  - If their server connection is too slow, maybe our script is timeouted (you need increase timeout in script - default is 30 seconds)
  5. Currently not support because it's just a PHP class, it's not application
  6. It depends on target server speed, average time is about 5-10 seconds per email
  7. If it is application issue, I can help. But it is infrastructure, maybe you need supporting from server/hosting provider

  Hello, at the moment, your script can run with bulk emails?
• 
  Nov 22, 2021
  donamkhanh Author

  Hi Tonyhoang,
  
  Yes, it can run with bulk emails but for your requirement, you should setup as much worker processor as possible. E.g: 1 worker can handler 100 emails/time => you need 100 workers

  Hello,
  If i use your this class for bulk email verify .
  So what do I need to get attention to do it?
  For example:

  Hi Tonyhoang,
  
  Currently it supports maximum 1000 emails per time (it just a config number in code). You should separate to small chunk and run on parallel CLI for better performance
  
  Please note that the result is more accurate if you setup your server as a SMTP server and some email ports are not blocked (e.g port 25)
  
  Thanks!

  if I use smtp of gmail what's happend when I process for 1000emails/time?
•

  donamkhanh Author

  You don't need to use Gmail SMTP. I mean, you should setup your server which are running this script as mail server to make sure all outgoing requests are treated as valid HELO command

  Hi ocbarbi!
  
  It depends on your need but in my opinion, DigitalOcean, Linode is suitable for me. You should ask them to enable port for email service (25, 465 or 578(

  Chào em! Hiện tại script này chỉ check mỗi lần 1 email em nhé. Mặc dù em có thể để trong vòng lặp để check nhưng sẽ ảnh hưởng hiệu năng.
  
  Anh đang suy nghĩ về việc cung cấp thêm bản nâng cao để hỗ trợ import danh sách email. Cảm ơn em đã quan tâm!

  Hi Cueup,
  
  Unfortunately, this version does not support bulk verification (although you can put this script in a loop)
  
  I'm going to add this feature on advanced version.

  It would be nice if you can make this a bulk email verification tool. If you can do that, i will surely buy. And also work on the interface as well.
