on what you posted, you need quotes around the email addresses:
myMail.From="mymail@mydomain.com"
myMail.To="someone@somedomain.com"
Also, this is not right:
myMail.Sendset
The "Set" should be on the start of the next line:
myMail.Send
Set myMail=nothing
>>uploaded this script (as an .asp file) on a free asp-supported remote server
>>>CDO.Message.1error '80040220'
The "SendUsing" configuration value is invalid.
Do you know if the server is running a local smtp server? Most likely it is NOT. On the tutorial page you posted, you basically need to use the last example, but you need to modify:
"smtp.server.com"
with the value of the appropriate smtp server. Contact your webhost and ask them what is their smtp address. As documented on the comment of that example:
'Name or IP of remote SMTP server
you can use either an IP address OR a domain name.
