Saya hanya melihat jawaban yang lain dan saya kira saya tidak pernah menulis solusi yang saya implementasikan. Ternyata python imaplib sangat mudah dan saya menulis skrip yang sangat cepat. Cegah beberapa perubahan (misalnya, menganonimkan berbagai USERNAME saya, EMAILPASSWORD, WORKDOMAINNAME, MYGPGKEYID). Saya juga tidak hanya mengirimnya terenkripsi; tapi tambahkan subjek dengan nama pengguna pengirim dan letakkan beberapa item header sebelum GPG (kalau-kalau saya membacanya di ponsel saya dan tidak dapat mendekripsi).

# This shelf (a persistent python dictionary written to file) has as its key
# the IMAP message ids of all emails that have been processed by this script.

Saya kemudian menambahkan baris-baris berikut ke crontab saya (skrip di atas bernama mail.py di dalam direktori yang disebut mail), jadi itu akan berjalan setiap 5 menit selama jam normal di hari kerja (MF 8-7 malam) dan lebih jarang di jam lain . (crontab -e)
