+# ----------
+# Fix Maildir Size
+#
+#     falls sich die tatsächliche Größe einer E-mail im Maildir Format 
+#     von der Größenangabe im Dateinamen unterscheidet, dann läuft
+#     dovecot auf fehler.
+#
+# Es gibt 2 Möglichekeiten das zu verhindern:
+#
+#     1. in der dovecot.conf (z.Bsp. in 10-mail.conf deb Parameter
+#        'maildir_broken_filename_sizes' auf 'yes' setzen
+#
+#              maildir_broken_filename_sizes = yes
+#
+#
+#     2. Die Größenangaben im Dateinamen korrigieren. Dafür gint es ein Skript
+#        namens 'maildir-size-fix.pl'. Dieses Skript steht bei Githup's
+#        'dovecot/tools' zur Verfügung:
+#
+#              https://github.com/dovecot/tools
+#
+# Das Perl-Skript maildir-size-fix.pl ist ein Werkzeug, das im Dovecot-Projekt 
+# verwendet wird, um Probleme mit der Größe von Maildir-Dateien zu beheben.
+#
+# Nützliche Optionen 
+#
+#     - add_missing_size: Fügt die Größeninformation hinzu, wenn sie fehlt.
+#
+#     - fix_existing_size: Überprüft und korrigiert bestehende Größeninformationen.
+#
+#     - recursive: Scannt das Maildir rekursiv, um auch Unterordner zu berücksichtigen.
+#
+#     - verbose: Ermöglicht detaillierte Protokollierung der Vorgänge.
+#
+#
+# ---------------------------------------------------------------------------------------
+#
+# Jede E.Mail in einem Maildir Ordner ist eine eigene Datei, dess dateiname üblicherweise
+# die Größe der datei selbst enthält (..,S=<dateigrösse>,W=..)
+#
+# ein typische Datei innerhalb eines Maildirordners sieht so aus:
+#
+#     1755713024.M837247P2624513.rage,S=38568,W=39101:2,Sc
+#          |            |          |
+#     Zeitstempel       |       Hostname  
+#                    eind. ID 
+#
+#     S= und ,W=: Dateigröße und "Weighted size" (für IMAP/Quota).
+#
+# wobei die flags folgende bedeitung haben:
+#
+#            +-------+-----------------------------+
+#            | Flag  | Bedeutung                   |
