Speaking as a user of Thunderbird, I have ~20GB of E-mail (including archives which date back well over a decade if not further), split across a few accounts plus the "Local Folders" non-account. It's divided into a total of 422 different mail-client-displayed "folders" (although some of them are parent-folder only, they don't contain actual messages), each of which is stored as a single file (not mbox or similar, but the internal "Mork" database format, which as I understand matters even Thunderbird may now be moving away from). That averages out to ~47MB per file. After discounting the otherwise-empty parent folders, the realistic figure is actually probably somewhere in the 100MB-200MB range. When a given mailing list's folder gets too large for my taste (or large enough that I start to notice delays reading or writing that folder), I create a separate "archive" folders for it by year, and move previous years' mail from that folder into those per-year archive folders; this tends to happen when the folder's contents reach somewhere between 10,000 and 20,000 messages. This isn't necessarily a particularly ideal way of handling things, but it's worked well for me thus far. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
