Help! How can I send email automatically without having user loging on?

[Celeste]

Hi,

My application needs to send email periodically without user interference. I tried MapiSendMail but I have to already logged on to my internet server for it to work. I want to be able to log on when I need to send the email then disconnect/log off when I am done without users doing anything. Is there a way? Thanks for your help.
