For another option to try. Not sure if it works with 98se though.
go to this website
and download the ansmtp installer (link on page)
go to the directory where you installed the ansmtp
(default is C:\Program Files\AdminSystem.NET\ANSMTP)
go to samples\vbs scripts
right click and edit the sendmail.vbs.
right at the bottom of the script is information you need to edit. the line is 'send. the first quotations is the sender, second quotes is the recipiant, third is the subject, fouth is body, last is the SMTP provider (can be you ISP provider).
change the values as needed and test by double clicking.
when you have changed the info don't forget to remove the ' in front of the send command.
To attach a file just remove the ' infront of oSmtp.AddAttachment "c:\test.txt" and put the path to your file in the quotation marks
now create either create a scheduled task to run this file or put a shortcut into you startup folder (under start).
