POP3 Mailchecker (with custom server list)

Soo hier ein POP3 Checker denn ich schon vor geraumer Zeit zusammengehackt habe, der aber noch prima funktioniert.

Die Maildaten sollten entsprechendes Format haben:

Code:

---

test@gmx.de:passwort

---

wobei der Delimiter (Doppelpunkt) auch ein anderer Buchstabe sein kann, wenn dies entsprechend beim Programmaufruf spezifiziert wurde.

Usage

Code:

---

[17:18:48] s3rb31@archbase:~/code/mailchecker $ ./mailchecker.py
Usage:
        ./mailchecker.py -i <inputfile> [-d <delim>] [-s <srv-list>]

        <delim> defaults to ':'
        <srv-list> defaults to 'popdata.txt'

  Use the '>' operator to redirect the output to any given file,
  for example:

        ./mailchecker.py -i inputfile.txt -s srvlst.txt > C:\data\outputfile.txt

Man kann die Liste mit den POP Server natürlich beliebig erweitern. Falls jemand da noch Listen hat darf er die auch gerne Posten!

Kleiner Verbesserungsvorschlag: Wenn Anbieter nicht in der Liste evtl standard subdomains/ports probieren.
Ansonsten sieht das Script nicht schlecht aus.

Erstmal Danke fürs Feedback und schön das es gefällt.

Zitat von schteal

jo sehe ich ähnlich. vlt. gibts ja auch ne möglichkeit da bei thunderbird via api die serverinfos abzugreifen o.Ä. ?

---

Wie meinst du dass?

Bei Thunderbird wird dir, wenn du ein Konto hinzufügst automatisch die subdomain/der port erkannt.

Tatsächlich hat Mozilla schon ganze Arbeit geleistet.

Code:

---

https://svn.mozilla.org/mozillamessaging.com/sites/autoconfig.mozillamessaging.com/trunk/

Edit: Es gibt auch Code um selbst eine Datenbank zu verwalten wenn ich das richtig gesehen hab. Evtl. überführe ich das ganze mal in SQLite3 (so scheint Mozilla das auch zu usen), dann kann man mit Python einfach die Domainendung extrahieren und via SQLite3 den passenden Server abfragen.

Momentan hab ich leider alle Hände voll zu tun, also wenn sich jemand berufen fühlt: nur zu.

aber auch bei unbekannten domains werden die standard-dinge probiert.
smtp.domain
pop3.domain
pop.domain
imap.domain
und dann halt die passendne ports 993,995,110,143,25,465
