Email is not sent

[yanbor]

I'm trying to send email from my web site using SMTP:

 Dim iMsg As MailMessage
        iMsg = New MailMessage
        Dim addrs(1) As MailAddress
        addrs(0) = New MailAddress(towhom)
        addrs(1) = New MailAddress(fromwho)
        iMsg.From = New MailAddress(fromwho)
        iMsg.To.Add(addrs(0))
        iMsg.Bcc.Add(addrs(1))
        iMsg.Subject = subj
        iMsg.Body = textbody
        '----------------------------------------------------
        Dim ret As String = String.Empty
        Try
            ' set up smtp client And credentials 
            Dim smtpClnt As New SmtpClient("relay-Hosting.secureserver.net")
            smtpClnt.UseDefaultCredentials = True
            smtpClnt.Port = 25          
            ' send the message 
            smtpClnt.Send(iMsg)
            'inform user that message has sent  
            ret = "Email was sent to: " & towhom & " with subject: " & subj
        Catch ex As Exception
            ret = ex.Message
        End Try
        Return ret

It returns that Email was sent, but I did not get it.

What I'm doing wrong?

Hey @yanbor,

Not sure what language you're using to script your form mailer, but as long as you have 'relay-hosting@secureserver.net' specified as the relay server via port 25, then SMTP should be sending. Our hosting teams have confirmed this still works via test SMTP and PHP mail scripting resources.

This is a function in ASP.NET code behind. It gave me notice, that email is sent, but it never did come to the user. And I check all folders: All Mail, Spam, etc...
