I have an Exchange5.5 running on a Windows2K server. I want to assure that my system always runs well, so every half an hour I send 1 mail from my mail client to my mailbox in the Internet and 1 mail from Internet to my mail client. If I receive mails both by my mail client and mailbox in the Internet, it means that my mail system is working well. Up to now, I have done this job manually. Do you know how I can do it automatically ? Thanks in advance.
