What did you fail to install? The source code does not need any installation, you can run it directly through visual studio2022

I installed the visual studio 2019 as the instruction said, I used the EmailVerifierPro application, and keep asking me to download .net, let me install the visual studio 2022. I will keep you posted

I finish the visual studio 2022 and I still get same problem, I need to send you an image showing you what is the problem.

ok bro

how can I send it ?

you can send us telegram or whatsapp

do you have intall netcore 5.0?

ok, i will check it

Please turn off the firewall and anti-virus software to see if it is successful!

The telnet common phrase detects whether a local port is open to the outside world, or (remote service) whether a port of the remote server can be connected. If telnet fails, consider whether this port is blocked by a firewall.

i have tried on newly formatted system with no antivirus and no firewall blocked, another email validator application is working properly

Okay, thank you for confirming the problem, please give a 5-star review

hi,bro, we need your 5-star review

i mean to say i have another validator that is working fine in same system but not this one is working

5 star is for sure, you developed very nice tool, every new tool has some bugs and issues at the very initial levels..

Because this verification is sent based on a TCP connection, anti-virus software and firewalls will affect it, and thank you very much for your evaluation

Please check whether the network is normal! You can try a few more times

let me reachout to you separately through support tab and not through the comment section

Is there any specific error?

The code is giving an error for all the emails “The SMTP sservice is not available”.

As per your suggestion 1) I tried running the program several times, however it didn’t help. 2) I have checked the internet and it is working perfectly at a speed of 200MBPS. 3) I have given my own email ids (gmail/yahoo and custom domain etc.) for verification to ensure email ids are valid; however the response is the same for all the email ids.

Can you send me your email list? Can i test it？

I can not send my email ids in public under comments section, however sending you separately through support tab.

After I tested it, everything was normal and all passed the verification

There is no problem in my test, So, I guess it is a problem with your network. You can import an email address and track it in the source code to see what the error is!

There is no other error except afforsaid error. As per your logic this condition will true “if (mxRecords.Count > 0)”, which is always returning “The SMTP service is not available” in my case.

I understand that the code might be running on your machine, which is the basic sanity test before putting your code on codecanyon for sale.

I am looking for some support to understand why code is not running on my machine. It looks like there might be version mismatch for the dotNET or some other dependent library which might be causing an error on my machine. I am having below setup: Microsoft Windows 11 Professional Visual Studio Professional 2019 .NET framework version 4.8.04161

Kind request: Kindly remove the above link for the screenshots that you have shared, as it still reflecting my identity.

Ok, I have deleted the picture, please set a breakpoint yourself to track the specific error on your machine! There is no problem with this condition, because the above delivery test cannot be delivered, even if it is greater than 0, it is useless

I tested it on another machine with windows 10 and a different network, however the same issue.

On debugging visual studio code, it is SMTP client timeout. As both EmailValidatorException.cs and SmtpClientTimeoutException are having empty functions, the parent function is exiting through “The SMTP service is not available”

If you have some time and willing to support, I can share my Anydesk ID to work with you to rectify the issue. It might be some specific issue, however I hope it will help other buyers as well.

If it is overtime, it means that the communication between your network and the server is too slow. Please set a larger timeout in the SmtpClient.cs file.

if (!tcpClient.ConnectAsync(this.host, this.port).Wait(5000))

Increasing timeout is not helping out, code is giving the timeout after given time. It is clear that code is not able to establish a TCP connection with given SMTP host/port. Let me know if you want to see the issue over Anydesk OR want me to share some more information.

If the TCP connection cannot be established, it can only indicate a network problem, whether you have set up a network proxy, etc., or it may be that the firewall of the machine is blocking the TCP.

As I mentioned above, network is working fine. I have tried the program with disabling antivirus as well as windows firewall, however no luck.

Despite trying on two different machines/OS/network, the script is not running for me as expected. Looking forward to have your support in debugging.

If it’s a TCP connection problem, it’s useless for me to debug

We don’t have a complete understanding of your code. From the debug seems to be SMTP timeout, however not sure about the root cause. Based on your prior experience and code knowledge, can you list out some checkpoints that we should follow to debug?

As your other clients might face a similar issue, I would appreciate if you can help in getting the issue rectified.

Test the mail you provided on my computer and everything is normal. If it is because of the TCP timeout, the reverse speculation is that the network or firewall is a problem, which means that the TCP and the mail server cannot be pinged.

As I mentioned, we tried this application on different computers in different combinations, however no success.

Let me know if there is a way we can get some support to make it working on our machines OR we need to debug it of our own?

In the later case, we will writeoff the expenses internally in our books and consider it as another non-working software that we have purchased.

BTW, I have purchased your other products as well. All of them are working except this one.

I spent a lot of time providing technical support and helping you analyze the problem, and I also tested the results on my computer! The rest needs you to solve it

I have time to watch tomorrow,

can you give anyesk code

shared anydesk code separately through support ticket
