Send Mail Problem

[Max]

hi

I used mailmessage object to send the mail, my smtp server don't
require authentication, when i try to send the mail it shows error.
following is the code to send mail.

Dim mymail As New MailMessage
Dim smtp As SmtpMail
smtp.SmtpServer = "mailhost.gujarat.gov.in"
mymail.To = "ma****@cybersurfindia.com"
mymail.From = "mahesh (check mail delivery)"
mymail.Subject = "check mail delivery"
mymail.Body = "hi this is to check mail delivery"

mymail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport",
"25")

mymail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl",
"true")
Try
smtp.Send(mymail)
Label1.Text = "Mail sucessfully deliverd"
Catch ex As Exception
Label1.Text = ex.Message & "<br>" &
ex.GetBaseException.ToString
End Try

here i have add smtpserverport and smtpusessl fields only i have not
added smtpauthenticate.

now when i add smtpauthenticate=0 it shows same error.

if i remove all the fields and olny assign smtp.SmtpServer if through
following error.
Could not access 'CDO.Message' object.
System.Runtime.InteropServices.COMException (0x8004020E): The server
rejected the sender address. The server response was: 501 : domain
string is NULL.

Please Let me know if any one know the solution

If you're using IE and it crashes, try another browser like firefox.
Some recent IE update ... blows up your browers when going to the
