having trouble sending mail via sendmail

I have tried to setup a sendmail command,
using an SMTP server that I have working in ms-outlook
but i am getting an error message
in options I setup
SMTP, MIME:none, text/plain, SMTP server the POP servername

and SMTP sender address my address on the popserver xx@yy
the MailSend( " same sender address xx@yy, "my email password", "destination email", "subject",

and "message")
I get a 'mail server not responding' even though I have
ms-outlook open on same server and this is functioing.

Can you suggest something that I might check that I am doing wrong?
The only question I see is that I am specifying my user email address
on both options and the MailSend statement

i have it working, I should have used smtp address not the pop address
for sending email
