Expunge - Skript für IMAP-Server

Milan · Samstag 20. Juni 2009, 23:53

Hallo Leute, ich hab ein kleines Problem und nicht die Fähigkeit es zu lösen, da ich das IMAP - Protokoll nicht wirklich kenne. Mein Uni-Mailaccount ist nahezu voll weil mir ein Kommilitone sehr große Anhänge geschickt hat. Nun werden bei IMAP ja Nachrichten nicht direkt gelöscht, sondern nur via FLAG als gelöscht markiert und nicht mehr im Client angezeigt. Kann mir jemand ein Skript bauen, dass einfach nur mal schnell ein Login auf einen IMAP Server durchführt und auf jeden dort vorhandenen Ordner ein Expunge-Kommando absetzt? Ich habe leider schon erfolglos Google bemüht um entsprechende Codeabschnitte zu finden und inzwischen auch via offlineimap mal den ganzen account gesichert. Leider finde ich nix was mir hilft, aber so schwer kann das theoretisch doch nicht sein, oder? Wie gesagt, ich kenne das Protokoll nicht (benutze es aber ganz gerne in verschiedenen Clients auf meinen daheim und in der Uni verteilten Rechner

und kann mir deswegen leider nicht selber helfen...

viele Grüße und danke!

Hab mir nun doch helfen können, zumindest für meinen Servertyp (Cyrus IMAP4 2.2.12) ... Bitte allerdings um Bestätigung, obs auch bei anderen funktioniert

Code: Alles auswählen

#!/usr/bin/python
import getpass
import imaplib
import re

#python >=2.4
#MBOX=re.compile("""\s+(?P<quote>["'])?(?P<foldername>[^"']+)(?(quote)["'])\Z""")
#python <2.4
MBOX=re.compile("""\s+["']?(?P<foldername>[^"']+)["']?\Z""")

SERVERNAME = ""
USERNAME = ""
PASSWD = ""

def parsefolders(response_list):
	l = []
	for line in response_list:
		m=MBOX.search(line)
		if m is None:
			continue
		l.append(m.group("foldername"))
	return l

if __name__ == "__main__":
	if not SERVERNAME:
		SERVERNAME = raw_input("Server: ")
	if not USERNAME:
		USERNAME = raw_input("User: ")
	if not PASSWD:
		PASSWD = getpass.getpass("Password: ")
	server=imaplib.IMAP4_SSL(SERVERNAME)
	server.debug=4
	try:
		server.login_cram_md5(USERNAME,PASSWD)
	except imaplib.IMAP4.error:
		server.login(USERNAME,PASSWD)
	folder_response=server.list()
	assert folder_response[0].upper() == "OK"
	folders = parsefolders(folder_response[1])
	for folder in folders:
		server.select(folder)
		server.expunge()
	server.logout()

gibt zum Beispiel diese nette Ausgabe:

wahrscheinlich letzter Post, habe noch ein paar debug ausgaben hinzugefügt

wäre trotzdem nett, wenn mir jemand bestätigen könnte, dass es bei ihm auch läuft. vor allem wegen dem parsen der Ordnerstruktur hab ich bedenken, da ich da nicht sicher bin, was das Protokoll genau vorsieht.

Code: Alles auswählen

#!/usr/bin/python
import getpass
import imaplib
import re

#python >=2.4
#MBOX=re.compile("""\s+(?P<quote>["'])?(?P<foldername>[^"']+)(?(quote)["'])\Z""")
#python <2.4
MBOX=re.compile("""\s+["']?(?P<foldername>[^"']+)["']?\Z""")

SERVERNAME = ""
USERNAME = ""
PASSWD = ""

def parsefolders(response_list):
	l = []
	for line in response_list:
		m=MBOX.search(line)
		if m is None:
			continue
		l.append(m.group("foldername"))
	return l

if __name__ == "__main__":
	counter = 0
	if not SERVERNAME:
		SERVERNAME = raw_input("server: ")
	if not USERNAME:
		USERNAME = raw_input("user: ")
	if not PASSWD:
		PASSWD = getpass.getpass("password: ")
	server=imaplib.IMAP4_SSL(SERVERNAME)
#	server.debug=4
	try:
		server.login_cram_md5(USERNAME,PASSWD)
	except imaplib.IMAP4.error:
		server.login(USERNAME,PASSWD)
	print "logged in..."
	folder_response=server.list()
	assert folder_response[0].upper() == "OK"
	folders = parsefolders(folder_response[1])
	print "got folders:", ", ".join(['"%s"' % folder for folder in folders])
	for folder in folders:
		server.select(folder)
		print 'processing folder "%s" ...' % folder
		typ,data = server.expunge()
		lenght=len(data)
		if lenght > 0 and data[0] != None:
			print "\tpermanently removed %i mails." % lenght
			counter += lenght
		else:
			print "\tno mails permanently removed."
	server.logout()
	print "logged out. altogether, removed %i mails permanently." % counter

gibt den output:
