Send Mail Using SMTP

[mahehs_k_anjani]

hi

I am using System.Web.Mail.MailMessage with System.Web.Mail.SmtpMail to
send mail. now the my question is,

Is it compulsory to add fields smtpauthenticate, sendusername and
sendpassword fields to MailMessage Object????.

mm.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate",
"1")
mm.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername",
SMTPEmail)
mm.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword",
SMTPPassword)

Which fields will i have to add if my SMTP Server doesn't require
authentication.

HI,
you need not add any of the above 3 fields to send a mail from your local machine to any Email id. what you need are : from , to , Subject
thatz all.. if you have any doubts you can mail me at svs_i43@yahoo.com

gud luck.
