Thanks Remy In article <46eb5f74$1@newsgroups.borland.com>, no.spam@no.spam.com says... > Anything in an email message can be faked.

What if I atatch a file that include a key, that changes every day and then on arivel I check if the key is the right one for the day. And istead of relying on the email date I write the date in the subject. The mail client could then download the new keys from a server that required logon Could that work ? I am a little afraid of that encryption stuff it looks very difficult. Thanks in advance Kind regards Asger
