My application need to send mails everyday to the people. For that I have written one Dtml method. which will refresh every 24hr.(using html tags.) But for that, that page should be running in the browser always.

This sounds like a job for cron: man cron man crontab If the job needs to get infomation which is held in Zope, you'd need to write a small HTTP client in Python which gets the info it needs by querying the Zope server just as if it was a web browser being driven by a human, formats it, and sends the email. Another approach would be to look into xmlrpc. But understand: the client works _outside_ of Zope. This is necessary to run it as a cron job, which is the best way to run a timed process under Unix/Linux. Good luck! -Andy PS: Please don't send HTML email to the list! :-) -- Andy Gimblett <andy.gimblett@ftech.net> Programmer Frontier Internet Services Limited <www.frontier-internet.ltd.uk> Tel: 029 20 820 044 Fax: 029 20 820 035 Statements made are at all times subject to Frontier's Terms and Conditions of Business, which are available upon request.
