Sending mail using asp.net w/ VB script

[trent101]

Hey,

In my site I have a contact page that is used to send emails to the owner. I have looked at several tutorials and have written the vb code needed. When I submit the form I get this error

System.Runtime.InteropServices.COMException: The transport failed to connect to the server. it gives me two http exceptions - 0x80040213 and 0x80004005.

Now the code that it sais is the porblem is sending the mail (SmtpMail.Send(objMM))

So I am just wondeing what this is actually saying. I am using my mail server that I obtained from my host (mail.mymail.com.au) and have specified this correctly in my code.

Is it a problem with my smpt server? That I need to take up with my host? Or is it another problem? I have read articles that explain about bigpond controlling port 25, and my isp is bigpond, could this be the issue?

Any help is much appreciated. Thanks for your time.

Are you using something like : ?


Imports System.Net
Imports System.Text


Dim mm As New Mail.MailMessage

mm.To.Add("a@b.com; ...")
mm.From = New Mail.MailAddress("...")
mm.Body = "hello!"
mm.Subject = "test"

Dim MailObj As New Mail.SmtpClient
MailObj.Host = "mail.otenet.gr"
MailObj.Send(mm)

TipGiver - Thanks for your reply.

After many hours working on this I realised the smpt service for my account with my host was not set up correctly. So after seeting it up I got it to work!

But now I have come accross another problem... One thing I wanted to eventually have was some kind of checking for email addresses, but I have just realised that asp.net has done it automatically. Im not sure if its my isp thats doing this or not.

If i enter an invalid email eg me@jshshs.com I will get an asp.net error page stating that the domain is not valid. Now this is good, but how do I control this?

The setup i currently have is if any field is not filled out correctlyI have code written that changes the label corresponding to it, to red in color. How do I determine if this error happens (invalid email domain) when someone submits the form, and stop the processing of the form and change one of my labels colors?

Again I thankyou very much for your time.

i dont think asp.net did anything for you!

try an invalid email at a known domain not hosted by your web host, you wont get the same error. its just that relaying isnt setup right or allowed, or you need to use authentication fields.
