Isn't the MailMessage.To property a MailAddressCollection though? can't you use Mail.To.Add(sToEmail)?

Which .Net version are you using, I get a compiler error just from trying to assign anything to To.

this code is working properly............i m using .net 2.0
the error might be occuring due to d the port no issue.......port no 465 work 4 gmail,n generally 25 is used 4 yahoo
