Well, on December 25, 2001, the hard disk that contained my /home
partition broke down. Fortunately, it was automatically remounted ro
so that I noticed the failure in the morning when fetching my mails,
and I could restore everything from the backups after I bought a new
disk :) It was an interesting experiance ...

Thus, the directory should be mostly unfragmented and only those mails
that came after Dec 25 should be affected by fragmentation.

Hm, I didn't notice effects of fragmentation yet. During the recent
years, I occassionally repartitioned my disks when new ones were
installed, and some partitions were copied over then. But I didn't do
that on a regular basis.
