Not exactly. Like I wrote in my message that's the example that I've been using. My idea _starts_ from there. Additional scripts are needed for the following: * How to do action_replace_with_url when there is a "magic word" in Subject-line? (and not when the attachemenet is bigger than something) * How to create a hash-named directory instead of changing attachement names? (Attachement names can have important information that is lost if the attachement names are changed. That's why I can not use the example script at all in production environment.) * How to (in a given condition) action_replace_with_url ALL attachements instead of just the big ones? * How to remove some known part (magic word) from Subject-line JOna On Thu, 15 Jan 2004, JOna wrote: > Hi, > We often need to transfer large files to people who's mailbox-quota > is limited.
