Quickstart
[!WARNING] Performance and memory usage:
mdedupimplementation is quite naive and everything resides in memory.If this is good enough for a volume of a couple of gigabytes, the more emails
mdeduptry to parse, the closer you'll reach the memory limits of your machine. In which casemdedupwill exit abruptly, zapped by the OOM killer of your OS.
