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.
Sounds like OP does something similar to what I do. They setup different email inboxes or catchalls for different services, then as email comes in it gets forwarded to paperless for OCR/search maybe?
I do this with paperless-ngx, where I forward some emails to a dedicated address that paperless watches. But I do this manually with emails that have important PDFs attached.
I’m not sure what the benefit is of automatically forwarding everything to paperless. Seems like duplicating emails unnecessarily, when email clients already have search/folder functions. Also email servers have mail rules so they can be sorted based on sender/recipient/subject/etc…
