mail.Body = "this is a sample body"

'This next line didn't help error but i was getting error prior to putting
this line in.

You don't need HTTP:// in front of the SMTP server, it isn't http, so
you dont need it :)

Also, Mcafee and other virus protection programs prevent
System.Net.Mail and System.Web.Mail from sending emails - it picks
them up as a mass mailing worm and generates the "Failure sending
mail" message. Be sure to add them to the list of allowed programs if
you think it will be a problem.

Thanks,

Seth Rowe
 
Ok, I kind of got it to work thanks to you guys.
I can send some emails successfully to 2 servers only (or websites).
Everything else gives me the error listed below and I know they are good
addresses.
I also used (e-mail address removed) and same error (which is a place to test
email).
If I go to outlook (same computer same time) I can send to all these email
addresses without error.

"Mailbox unavailable. The server response was: <[email protected]> No
such user here"}
System.Net.Mail.SmtpFailedRecipientException'

Thanks again in advance
