Hello,
Hello Muhammad,
Hi Luis,
Thank you for posting your inquiry.
-
We have tested the bulk sending of emails generated from Template Engine and it works. Can you verify if you are behind some company wide firewall or DNS settings that is not allowing to send emails out of the network? Please share the SMTP Log of your test application and share that with us. Please make sure that you are using the latest version of the API at your end. Please also try your sample at your end on a different PC and share your feedback with us if you get on the other PC as well?
-
The SmptClient once initiated in application remains alive during the session and we haven’t faced any issue while using such a single client of the API and it works fine. So, you can use it in a singleton for your requirements.
-
It may be some issue with DNS or network settings at your end they may be stopping the EmailValidator to validate the external email addresses. It seems that this is linked with the point 1 above and we may get more information about it once the log file is provided.
Also, please try disabling the Internet Security/AntiVirus software at your end and share your feedback with us whether it works or not.
Hello Muhammad,

Hi Luis,
We understand that there might be some issue with the Aspose API that we need to reproduce at our end first before forwarding to our Product team.
4. Please follow this issue [here](https://forum.aspose.com/t/23363)
. It is always good to create a new thread and report each problem separately in a new thread so that the issues don’t mix up.
5.a. Please follow the link shared above for creating a sample application. When you will run this Windows Form based application, it will generate a log file. Once you hit the exception, please share the log file with us so that we can investigate the issue further and share our feedback with you.
5.b. Please add the code for bypassing the Exchange Server Certificate and see if it helps. This should be added to the start of the application.
Also, is it possible for you to:
- Test this issue from a different PC and share with us if it works or not?
- Please share the .NET Framework, OS & Visual Studio application information with us.
- If possible, please create a test account on your server and share those with us. We shall try to use these for reproducing the issue at our end and assist you further.
