I am developing a program in vb.net which needs to connect directly with my mailserver (postfix) to send emails which will be directed towards email to sms transmissions. My mailserver is otherwise working properly and I am not having any problems with it functionally (it sends and receives without problem on squirrelmail). I also attempted a smtp test with http://www.nanogenesis.fr/ and it is reporting the same error, I am thinking this is a problem with my postfix settings. My application is currently running the code (and could easily run authentication also):
'create the mail message
Dim mail As New MailMessage()
'set the addresses
mail.From = New MailAddress("[email protected]")
mail.[To].Add("[email protected]")
'set the content
mail.Subject = "Page"
mail.Body = "this email is to test the paging system"
'set the server
Dim smtp As New SmtpClient("fasttrackdispatch.com")
Dim errmsg As String
'send the message
Try
smtp.Send(mail)
Console.Write("Your Email has been sent sucessfully - Thank You")
Catch exc As Exception
errmsg = "Send failure: " & exc.ToString()
End Try
on my software side this is appears to be working however the email doesnt send,
the mail.log file states
