I have looked at paperless in the past and just asked why? I just spent a little time setting it up to see what it was about, then I spent hours configuring it and my email server creating paperless email addresses that other emails forward to! I cannot believe I have lived this long without it.
I forward emails to my paperless address, and never thought of using drag/drop. How does this work for you? I remember having trouble getting paperless to see emails that were already read, or otherwise it would constantly try to reupload the same files. Do you watch a specific folder and then have paperless move to a different folder on consumption?
