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 have an paperless account and shared it with my user, but you can also just integrate 2 accounts in one email client.
Guess I should create a sieve filter to look for relevant mails and auto-copy
