.Net Mail Duplicates

Question

Hello everybody, I am facing a weird problem in production, not happening in Local machine.

I hosted an application in godaddy that has a aspx page where it collects the email addresses from the text fields (txtTOEmail,txtCCEmail, txtBCCEmail).

When I call the send method on the mail object, the mail is sent twice. But this is not happening in my local machine.

NOTE : In my local machine I am using GMAIL smtp. In prod I am using Godaddy SMTP.

Any ideas and advices are welcomed.

Thanks in advance.

Answer 1

Are you using the same email for more than one of the fields? If so, it could be a difference in how GMail sends vs. how Godaddy sends. GMail probably notices the two email addresses are the same and only sends one email. Godaddy may not check that.

Answer 2

For starters, you can dump the e-mail to a folder instead of sending it to the SMTP server to see if you actually send it twice:

  <system.net>
    <mailSettings>
      <smtp deliveryMethod="SpecifiedPickupDirectory" from="[from address]">
        <specifiedPickupDirectory pickupDirectoryLocation="[dump directory]" />
      </smtp>
    </mailSettings>
  </system.net>

Answer 3

Can you show the code that is sending the email? It is possible that GMail is consolidating two of the same address into one email instead of sending it twice.
