I am looking for a system to avoid duplicate large emails!

E.g.:

Peter found a nice pps file and send it to a couple of friends. One of them send this email to a couple of others (well, not only others, I am included again), ....

I get the same email then over the time 10 times!

I am looking for a way that people can "upload" the so important information and only send info about a new file stored there (or just let each friend subscribe via RSS).

Is something like that available or where to start?

Yes, it's called web site :)

I.e. you may try some CMS (content management system), or Wiki, or even you just can setup a simple ftp server.

You can try google groups as well. One of you will need a free google account to create the group, but anyone can be invited to join. Not sure how much disk space you get for files, but worth checking out.

Inside a network(e.g. a companies network) there was some sort of mail server which actually could do this(so not 200people have the same attachment in their mail boxes, but they open 1 file directly from the server).

But unfortunatly I can't remember the name, I don't think it was exchange, rather Groupwise or something like that maybe? (sorry :( )

It's Exchange, actually, though they may have picked up the feature from someone else. I know Exchange 2003 has that feature, not sure if old versions do.

GroupWise acts in this manner too. Large attachments (over 2K from memory) are stored centrally in the post office. Any users whose mailboxes reside in the same post office will be accessing the same file associated to the attachment when it is requested. AFAIK most mailservers will work in this fashion? From a storage point of view it's good practice to use one copy of the same file.

But -- it's a source of lots and lots and lots of database corruption, and doesn't work if there's even a single address from outside of the Active Directory forest.

It's not so much the AD forest limits in so much as which server the mailbox is on. If you have mailboxes over multiple servers, each server will store a copy of the mail + attachment in it's message database.

I don't know of an Open Source mail storage system that'll do that, though. It does seem like something that the mail DB products aimed at the corporate/ISP market (eg, Cyrus) might have, or might be working on if they don't. Been a while since I've hosted my own mail, though...

(Michael, sorry you got this twice.)

Assuming you posted to the sender directly - I can't help but smile at the apology given the subject of the thread... Going back to the original post though, you can't really *stop* people from sending you the same attachment again and again. It requires user education that a website or fileserver is the best place to put attachments like that. You might want to consider a CMS. I've used drupal in the past and it seems pretty easy to use. Alternatively, maybe a blog is all that is required in which case typepad or wordpress spring to mind. All of these will support RSS feeds.
