SMTP troubles

Antonius Block · December 26th, 2014, 08:07 PM

Hello Imar,

following your explanations in chapter 9, I manage to send an email dropping it in a folder on my local hard drive, but I fail to send it both from gmail and yahoo accounts.

Excerpt from Web.config for yahoo

Code:

<smtp deliveryMethod="Network"  from="[email protected]">
      <network host="smtp.mail.yahoo.com" password="xxxxxxx"     userName="[email protected]" />
</smtp>

Excerpt from Web.config for gmail

Code:

<smtp deliveryMethod="Network" from="[email protected]">
        <network enableSsl="true" host="smtp.gmail.com" password="yyyyyy" userName="[email protected]" port="587" />
</smtp>

The error I get is the following:
From the script debugger in Internet Explorer
File ScriptResource.axd
Line: 940
Error: Sys.WebForms.PageRequestManagerServerErrorExceptio n: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

Can you give me some hints ?
Thank you

Hi there,

Try removing the UpdatePanel so you can see the real error message. Maybe that sheds some light?

Cheers,

Imar

The real error I get - both for Yahoo and Gmail SMTP - is the following:

Quote:

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.1 Authentication Required.

In the past, I had developed your Planet Wrox website in the 3.5 version of your book - on VS 2008 and Windows 7 Ultimate edition - and I managed to send emails from the ContactForm.

I've tried to launch the same old web site from my current VS 2012 on Windows 8.1 and I cannot send emails any more. I suppose the problem is somewhat related to Windows 8.

Can you give some hints ?

Thank you

Antonius

Hi there,

Are you 100% correct you modified the correct web.config? Your code looks fine as it sets up a secure connection.

Also, for Gmail, did you set up an app specific account? https://support.google.com/mail/answer/1173270?hl=en
