Your Web Form is throwing an 500 internal server error.  There can be many reasons for this errors but without proper exception handling/logging it is difficult to determine.  Try checking the Event Viewer for errors.

I recommend adding a try...catch to catch the exception message and stack trace.

Hi vaverbukh2,

When i am sending  email on my local machine email working fine but when i am trying to send from Development server i am getting this error:

According to your descriptions,we couldn't directly find the issue.Because there are many reasons why this error can be caused.

I suggest you could follow below ways to find the details error message.

First, you need to enable and see detailed errors of your web messages, because this is a general message without giving information on what's really happening for security reasons.

With the detailed error, you can locate the real issue here.

Also, if you can run the browser on the server, you get details on the error, because the server recognizes that you are local and shows it to you. Or if you can read the log of the server using the Event Viewer, you also see the details of your error.

<configuration>

<system.webServer>
<httpErrors errorMode="Detailed" />
<asp scriptErrorSentToBrowser="true"/>
</system.webServer>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>

More details,you could refer to:

Besides, I guess you may not use the right way to publish the app, you could refer to:
