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 got an unlimitted email package from a host, before my journey into self hosting. I use a different email address for everything I sign up to or need to confirm I am human with. They all forward to 6 or 7 different emails I check I have just decided that those email addresses would forward to paperless email address to keep stuff sorted.
*edit I get next to no spam, if I do I either close the email or tell the company they have had a data leak and close the email.
