Normally your ISP will provide an email account with an associated smtp 
forwarder for you.   Just set up your mail client program to use this 
account directly instead of sending through your own sendmail.  If you 
do want your sendmail to handle it (perhaps to get queueing when offline 
or to let programs send mail easily), add your ISP's smtp forwarder as 
your sendmail 'smart host' in /etc/mail/sendmail.mc:

dnl # Uncomment and edit the following line if your outgoing mail needs to
dnl # be sent out through an external mail server:
dnl #
dnl define(`SMART_HOST', `smtp.your.provider')dnl

(the 'dnl' is the comment token).
