Hi, thanks for you reply.
I'm using the port 25 as you can see below but its is not working.
May be I'm missing something. Could you please try to help me.
Dim email As IMail = builder.Create
Using smtp As New Limilabs.Client.SMTP.Smtp
Try
smtp.Connect("relay-hosting.secureserver.net", 25)
smtp.SendMessage(email)
smtp.Close
Catch ex As Exception
End Try
End Using
Best regards
Rogerio Picilli
