Using Postal on Azure with Sendgrid

[Andreas75]

Hi, i'm trying to use Postal on a web app hosted in Azure. But get this error:
System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed.

This is the code i'm using:

dynamic email = new Email("Test");
email.To = "[email protected]";
System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("azure_d3e************************[email protected]", "7N**********5C");
SmtpClient smtpClient = new SmtpClient("smtp.sendgrid.net", Convert.ToInt32(587));
smtpClient.Credentials = credentials;
email.Send();

My Test view:

To: [email protected]
From: [email protected]
Subject: Important Message

Hello,
This is a tests!!

My web.config smtp settings:

I use Postal with SendGrid in Azure (Web Apps). The only thing I changed was in the web.config.

 <mailSettings>
  <smtp from="[email protected]" deliveryMethod="Network">
    <specifiedPickupDirectory pickupDirectoryLocation="c:\email" />
    <network host="smtp.sendgrid.net" port="587" userName="{username}" password="{password}" />
  </smtp>
</mailSettings>

And then I just
dynamic e = new Email("view");
e.Send();

However, in your code, you have an SMTP client you instantiated, but you didn't do anything with it. Not sure if it was a copy & paste error. But, if there's nothing in your config, that would never work.
