Emails not sending

I have some custom code that sends an email when a particular event happens. This is a page with no visual interface, only responds when called from another website, ASP.NET 3.5, yada yada.

I know the page is firing because it is updating a SQL database properly. Just the email notification is not happening.

I am using the "no-reply" email address as the sending address. I've used both of these settings in the web.config:

Code:

<system.net>
    <mailSettings>
        <smtp>
            <network host="smtpauth.earthlink.net" port="xxx" userName="xxxxxxxx" password="xxxxxxxx"/>
        </smtp>
    </mailSettings>
</system.net>

Code:

<system.net>
    <mailSettings>
        <smtp from="[email protected]" deliveryMethod="Network">
            <network host="localhost" port="25" password="xxxxxxxx" userName="[email protected]" />
        </smtp>
    </mailSettings>
</system.net>

And the code I am firing in the page does this:

Code:

    public void SendMail(string mailFrom, string mailTo, string subjectText, string bodyText)
    {
        System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();

        mailMessage.From = new MailAddress(mailFrom);
        mailMessage.To.Add(new MailAddress(mailTo));

        mailMessage.Subject = subjectText.Trim();
        mailMessage.Body = bodyText.Trim();

        SmtpClient smtpClient = new SmtpClient();
        Object userState = mailMessage;
    
        //Attach event handler for async callback
        smtpClient.SendCompleted += new SendCompletedEventHandler(smtpClient_SendCompleted);

        try
        {
            //Send the email asynchronously
            smtpClient.SendAsync(mailMessage, userState);
        }
        catch (SmtpException smtpEx)
        {
            //Error handling here
        }
        catch (Exception ex)
        {
            //Error handling here
        }
    }

which uses this for error trapping:

Code:

    void smtpClient_SendCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
    {
    // Event handler for processing completion information after asynchronous email sent.

        //Get UserState as MailMessage instance from SendMail()
        MailMessage mailMessage = e.UserState as MailMessage;

        if (e.Cancelled)
        {
            //labMessage.Text = "Sending of email message was cancelled. Address=" + mailMessage.To[0].Address;
        }

        if (e.Error != null)
        {
            //labMessage.Text = "Error occured, info=" + e.Error.Message;
        }
        else
        {
            //labMessage.Text = "Mail sent successfully";
        }
    }

 

Hi,
I can't spot anything wrong other than the possible address building event.
Have you tried running a test with the message from and to hard coded?
All the best,
