With MIME encoded mails it is not, just a flat text-based database
of variable length entries.  If all your software agrees in
storing properly MIME encoded data, all is fine.
If not you have the ^From_ trouble.

 |mdir doesn't spam the worm like mbox does.

Which means re-encoding as necessary to avoid ^From_ quoting,
which not many do support (my s-nail for example does not :).
All the ASCII centrism .. was trouble.
It was the thorn .. in his mutter side.
She tried in vain .. but it never caused her nothing but shame.
