How can we improve Kerio Connect?

intercept msgs w/ large attachments and send link

when users send messages that are over pre-defined size, have Kerio intercept those attachements and replace them with a link to the file for the recipient to be able to click on the link and automatically and securely download the file. Then send an email to the sender informing them the file had been downloaded and by whom and prompt them to delete the file that was stored in the users' account.

    You can, let this use OneDrive, DropBox, and other file sharing service.
    But can also provide your own Dropbox like system for kerio.

    Have you seen that at your company:
    1.) A user sends a mail with a 50 MB attachment to 15 colleagues.
    --> Storage space on connect server: 16 * 50 MB = 800MB !!

    2.) External inboxes are full or limited in size, so mail cannot be delivered.

    Automatically replace attachment with a download-link at companies own Owncloud server.
    Total space needed in the above example: 50MB on cloud server.

    - Keep connect storage small
    - Keep backup fast. 800MB times x in every full backup....
    - Keep mails small for inboxes with limitations
    - Send mails with attachments as large as 1-3 Gig. (Depending on cloud settings)

    When a mail is set via webmail or Outlook or other clients:
    Connect server checks size of every single attachment. If it is bigger than a configurable size, the attachment is uploaded by connect server to a Owncloud/Nextcloud account.
    Nextcloud gives the share link back to connect server who replaces the attachment with the download link to the file.

    New settings in connect:
    - Strip off larger than xx MB
    - IP of cloud server
    - Login credentials (all mails use the same account for mail attachments, as links cannot be guessed)
    - Default Lifetime of Link
    - Default time to purge file from Owncloud/Nextcloud server
    - Max. upload size accepted by cloud server
    - ???

    For the sake of European Regulations: Do not only support cloud services like Dropbox.

    Nextcloud and Owncloud are free, secure and fast replacements at users premises.
    (Upload is also faster in LAN than to WAN location.)
    Nextcloud Setup with VMWare and image at in less than 30 minutes.

    This is a cool idea. There should be an option for the administrators to set the place for the attached files. In the Kerio store or external places like on the webspace from our webprovider. Maybe as a mirror.

    Yes please. This is the #1 issue with email. Users are never going to stop attaching large files to emails because in their mindset they want to "send" something and email is the obvious choice. There needs to be an automated way like this to strip the attachments from the message and replace it with links.

    I'd like to see this not as a one-off implementation (send, then delete file after download) but rather a global setting that governs both the maximum allotment all sent attachments should consume along with a cutoff date. Attachments wound then get automatically deleted whenever either the reserved size for all attachments is exceeded or an Admin-defined number of days have passed (e.g. 180 days). This is because users often want to check back when exactly they sent to whom and when. If all they found were text messages with (now inactive) links, it would just frustrate them. The cutoff date and storage size could be adjusted according to each businesses' needs.

    Since Connect already can send a bounce notice if message size (with attachments) is too large, why not have Connect send a message back with a link to the users account, offering to set up an "expires after x-days link to post the attachment and send out a download request? If the answer is "Not everyone uses SamePage," ok, then add a "Integrate with SamePage" option in Admin console.

    Kerio will automatically suggest this function when someone try to send mail larger than it is set up in kerio settings....

  • Kim Isaksen commented  ·   ·  Flag as inappropriate

    I was about to suggest this myself and I found this. Im puzzled over the lack of votes, it would be a great feature. Today we have to use some 3rd party sollution for this, and it isnt intuitive at all to the users. They have to drop the attachment on a different app icon, they never seem to understand when an attachment is too big for mailing, we have to distribute licenses to each user for our 3rd party app etc. Its a mess. Kerio should really look into this.

    The Problem
    Many Admins set their SMTP Server to get no Mails >10 or 15MB.

    The Solution
    Save the Fileattach on our local Server and send only a HTTPS Link to download the Attachent directly from our Kerio Connect Server.

    This would be a huge plus for us, our users would love it. A simple way to send files using a familiar interface. Add in a bit of security perhaps and you'd have a great tool.

    Some other mail server softwares have this functionality already implemented.

    We installed a good opensource software (filez). But have this service integrated would be great (space on server, Internet link no more down because a user sends a mail to everyonewith a big attached file, ...).
