Storage is cheap - really cheap. I bet automatically capturing images of all mail during sorting and archiving that for years is not only viable, but a vital investigation/intelligence tool. One would ask Mullvad for the cash payment dates[1], and cross-reference with all mail sent to a Mullvad postal address. One city-level datapoint on where user was, cross-checked with the latest IP address, where stamps were bought, and you've massively trimmed the list of suspects, especially if they are behind a NAT and sharing the IP.
1. They have to keep track of payment dates, which is a side channel.
