Mich hat heute eine Email erreicht, in der mir folgende Aufgabe beschrieben wurde (Ich hoffe mal Udo ist mit der Veröffentlichung einverstanden, hätte ich selber nicht besser formulieren können.):

Ich möchte eine Mail in Mail.app anklicken, danach sollte die Mail als pdf (wie unter Ablage Drucken PDF Als PDF sichern) in einem speziellen Ordner auf dem Schreibtisch mit folgendem Namen (Sendedatum, E-Mail-Adresse und Betreff aus Mail) gesichert werden. Der eventuelle Anhang sollte ebenfalls in diesem Ordner gesichert werden. Die Mail kann danach gelöscht werden.

zusammen mit dieser Aufgabenstellung und den ersten Code-Zeilen von Udo ist dann das hier entstanden (ich mag zwar GUI-Scripting nicht, aber das hier ROCKT ;-) ):

In habe mal auf das Löschen der Email verzichtet (das soll mal jeder lieber alleine rein schreiben), aber es scheint wunderbar zu funktionieren. Bin mal gespannt ob es auch bei anderen läuft…

Updates vom 29.09.2010 und 27.09.2011:

• Auswahl von mehren Emails wird nun auch möglich
• Abgesendete Emails werden als solche erkannt und in einem anderen Verzeichnis mit Empfänger-Adresse im Ordnernamen gespeichert (req. by Andreas)
• Lokale Email-Ordner funktionieren nun auch mit dem Skript

Update vom 18.02.2013:

Das Skript funktionierte leider nicht mehr unter 10.8… tja jetzt schon wieder… habe ich schon mal gesagt, dass GUI-Scripting doof ist? Ok, zudem spielte da auch noch Gatekeeper mit rein. Man darf Attachments nur noch im dafür ausgewiesenen Download-Order per Skript speichern. Anschließend darf man diese aber auch wieder verschieben, nervig, aber nicht sicher ;-)

-- Save Mail as PDF and it's attachments to folder
--  Created by hubionmac (29.09.2010)
-- 29.09.2010 
-- -Auswahl von mehren Emails wird nun auch möglich
-- -Abgesendete Emails werden als solche erkannt und in einem anderen Verzeichnis mit Empfänger-Adresse im Ordnernamen gespeichert (req. by Andreas)
-- 27.09.2011 made it work with local mailboxes, too
##2012-04-17 changed the way paths are formated (posix/mac) and now the script runs on 10.7 again =)
##2013-02-18 Updated code so that it works using 10.8.3 (new dialogs and new gatekeeper made this necessary)

Update vom 23.03.2014:

Das Skript funktioniert nun auch unter 10.9.2 (habe nun gewagt selber zu aktualisieren). Dabei hat sich in Mail selbst nichts geändert, aber nun muss jede Anwendung einzeln die Erlaubnis erteilt bekommen GUI-Scriping durchzuführen. Das Script also ab besten über ein richtiges Programm wie FastScripts ausführen, den Dialog abwarten und dann bei FastScripts das Häckchen setzen…

## 2014-03-23 Updated code so that it works using 10.9.2 The Dialogs have not changed, but handling GUI Scripting made this necessary. Now you will have to enable GUI Access for each single app that whats access... so this script app or the app running this script (e.g. FastScripts)
