Thanks for the feedback! This ifttt is only for Gmail --> Dropbox, my service supports any email client to any major cloud drive. Additionally, we automatically organize your attachments by filetype, so it's easy to find them later. And if you want to save on inbox space, we have the option of replacing attachments in incoming e-mails with the links to where they're stored on your cloud drive.
Once you know that a service like this exists you want it. I won't sign up, because I am unsure about giving another company access to my mail account. Do you know about a similar solution that can be run on an own server?
If you're looking for more robust/common software take a look at the "mpack" package of tools.
Syncing to dropbox is left as an exercise, but presumably you'd just configure your attachments to be saved into the magic folder, perhaps on a per-suffix basis. (e.g. ~/shared/attachments/jpg/foo.jpg)
I don't know of any solution that can be run on your own server, but that's a valid concern. Since I developed this product, I can tell you that we don't store any attachments and our communication with your email is fully encrypted.
That's fair, if you don't trust any cloud storage drives with your data, this might not be for you. Not sure what would make a cloud drive less trustworthy than an email provider, though.
It's not necessarily that I am worried about any of them, but it is much more likely that at least one of them will have a security breach than it is with just one provider.
For instance, I use Dropbox. If Box has a breach, I am fine. I am fine unless Dropbox has a breach. If I use This service, then my data is compromised if any provider has a security breach.
Sorry, I really don't but our IT has pretty strict rules about what we can do with our email. I'm guessing you would have to work directly with the corporate IT departments to make sure they can audit security.
