Mythos Inbox Zero

Das theoretische Grundgerüst zu Inbox Zero ist mir längst bekannt, doch mit Blick auf den aktuellen Stand meiner INBOX – 321 messages – hapert die praktische Umsetzung noch ein bisschen. Doch welch erlösendes Gefühl, als ich heute zufälligerweise folgenden Blog-Artikel gelesen habe:

Inbox Zero is a myth. And soon it will be a book about a myth. Really, it’s a term that geeks use so we can convince ourselves that we’re winning the battle against communication overload. We’re not winning. We’re just selectively forgetting certain emails, half-responding to others, and if worse comes to worse, switching communication platforms. That’s not winning, that’s running.

Nun, obwohl ich Inbox Zero noch nie ausprobiert habe schlage ich mich aus reiner Erfahrung sofort auf Sieglers Seite. Klingt irgendwie einleuchtend.

postfix unter Mac OS X 10.4 aktivieren (inklusive SMTP-Relay)

Obwohl es ein kostenpflichtiges GUI zur Konfiguration des postfix-Mailservers gibt, machen wir als Geeks die Sache lieber von Hand auf der Kommandozeile.

Da Apple postfix bereits mit der Standardinstallation von Mac OS X mitliefert, den Daemon aber nicht aktiviert, sind die Arbeiten relativ trivial. Wer nicht das erste Mal mit dem CLI in Berührung kommt und sich mit sudo und vim auskennt, sollte den SMTP-Server innert 5-10 Minuten am Laufen haben.

Wichtig ist, dass hier nicht der lokale SMTP-Server aktiviert, sondern auch gleich ein relayhost eingerichtet wird. In meinem Fall ist das der SMTP-Server meines ISPs Cablecom. Damit ist es möglich, Mails auch tatsächlich in die weite Welt hinauszusenden. Vorausgesetzt, man verfügt über einen SMTP-Account bei seinem ISP.

/etc/hostconfig

...
MAILSERVER=-YES-
...

/etc/postfix/main.cf

...
myhostname = mad4you.homeip.net
mydomain = mad4you.homeip.net
myorigin = $myhostname
...
inet_interfaces = localhost
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks_style = host
mynetworks = 127.0.0.0/8
...
relayhost = smtp.hispeed.ch
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =
...

/etc/postfix/sasl_passwd

smtp.hispeed.ch user@hispeed.ch:geheim

Sicherheitsvorkehrungen:

$ chmod 600 /etc/postfix/sasl_passwd
# chown root:root /etc/postfix/sasl_passwd

Anschliessend muss die Passwort-Datei gehasht werden, da die Angaben sonst nicht von postfix interpretiert werden:

# postmap /etc/postfix/sasl_passwd

Neustart des Daemons

# sudo launchctl start org.postfix.master

Test

$ echo `date` | mail -s "Dies ist ein Test-Betreff von der Kommandoziele" spam@eMeidi.com

Ein Blick in /var/log/mail.log zeigt umgehend, ob was rausgegangen ist oder nicht:

$ tail -f /var/log/mail.log
...

private at emeidi dot com

Ich war nie ein Fan davon und habe es auch nie angewendet:

So nobody needs to obfuscate their email address any more. I don’t think spammers really cared about obfuscation anyway, do you think they’re too dumb to use regular expression like /@|s*[s*ats*]s*/i?

Schön, dass andere Entwickler die Nutzlosigkeit dieses Vorgehens langsam, aber sicher einsehen.

Exekutiert die Academy!

Ein Mail, das gestern in meiner INBOX eintraf und ich 100-prozentig als Spam einstufe (ich hab der Firma meine E-Mail-Adresse nie bewusst übermittelt), darf von Gesetzes wegen nicht Spam sein – sagt der Versender:

Hinweis zu Artikel 3 des Bundesgesetzes gegen den unlauteren Wettbewerb (UWG): Diese e-Mail wurde Ihnen nach der manuellen Erfassung Ihrer Adressdaten in unserer Datenbank zugesandt. Sie kann also nicht als Teil einer Massenwerbung aufgefasst werden und verletzt somit Artikel 3 des UWG nicht.

Quelle: Mail der Academy for Best Execution für ein Weiterbildungs-Seminar „Strukturierte Produkte“ vom 18. Juni 2008 Zürich

Abgesehen davon: Solche Scheiss-Namen („Academy for Best Execution“) entstehen, wenn man deutschsprachige Marketing-Fritzen frisch vom gerade abgeschlossenen BWL-Studium weg Firmennamen austüfteln lässt – und zwar auf englisch, da dies heutzutage ja äusserst professionell klingt.

Ich jedenfalls verstehe unter „Best Execution“ nicht „Ausführung“, sondern „Exekution“, also das organisierte Töten von Leuten (meist Gefängnisinsassen in den USA) mit Strom oder Gift.

Google Mail-Limitationen

[…] Google will temporarily disable your account if you send a message to more than 500 recipients or if you send a large number of undeliverable messages. If you use a POP or IMAP client (Microsoft Outlook or Apple Mail, e.g.), you may only send a message to 100 people at a time. Your account should be re-enabled within 24 hours.

E-Mail nur noch mit Confidentially notice!

Wenn nun sogar schon Professoren beginnen, mit „Confidentially notices“ um sich zu werfen, ist es höchste Zeit, dem nachzuziehen!

Hier die Vertraulichkeits-Erklärung, wie sie mir für meine künftigen Mails vorschwebt:

CONFIDENTIALITY NOTICE: This email correspondence and any attachments may contain confidential and privileged information intended only for the use of the designated recipient(s) listed above. In accordance with the confidential nature of this information, this message and any attachments may contain legal, or other privileged information which may require a security clearance and could have negative ramifications as a result of tampering or hacking. If you are not the addressee, or the person responsible for delivering this to the addressee, you are hereby notified that you are not authorized to review, read, tamper with, encrypt, hack, disseminate, use, distribute, disclose, copy, electronically store, transmit, retransmit, deconstruct, syndicate, remix or otherwise create derivative works from, link to, link from, burn to disk, record, engage in eavesdropping of public reading or performance, otherwise reproduce the work via antiquated or as yet unfounded equipment or media, or take any action regarding the contents of this message. Doing so is strictly prohibited. If you are not the intended recipient, or have otherwise received this message by mistake, please notify the sender by replying via email. Destroy all copies of this original message (including attachments) to avoid prosecution and/or litigation. Furthermore, if you are the intended recipient of this message, federal, state or other local laws may prohibit you from engaging in unlawful copyright infringement regarding attempts to review, read, disseminate, use, distribute, tamper with, encrypt, hack, transmit, retransmit, disclose, copy, electronically store, deconstruct, syndicate, remix or otherwise create derivative works from, link to, link from, burn to disk, record, engage in eavesdropping of public reading or performance, otherwise reproduce the work via antiquated or as yet unfounded equipment or media, or take any action regarding the contents of this message. Use of this email and attachment(s) may not be used for legal purposes, or as evidence, without the prior notification, in writing, of all recipients contained therein, regardless of Fair Use dictates. The recipient(s) acknowledges that email is an inherently unsure format and that these correspondences may not be from the sender listed in the “From:” field. Email can easily be falsified or otherwise duplicated and the sender accepts no responsibility for potentially offensive materials that may or may not have been sent to the recipient, regardless of how they are received.

Opening this email message implies your agreement that you will not use, or encourage others to use, any unauthorized means for the duplication or distribution of this email message or any attachment(s), especially regarding sharing via peer-to-peer networks, whether personal or public. Packet sniffers or other devices used to intercept or access communications are frowned upon by the author(s) of this message and will not be tolerated as a means to foster authentic, wholesome communications. It is your responsibility, not the author’s, to ensure that any material you distribute from this email does not violate anyone’s copyright. Please note that there may be more than one copyright involved in any message – the text, the attachments and the performance or reading of said material, for example, may each have a separate copyright. You are responsible for getting any necessary permission and paying any necessary licensing fees for the email or other material you choose to reproduce. If you violate the copyright laws, there may be fines or criminal charges brought against you, even if you don’t get any commercial benefit from the illegal copies.

You agree, if purchasing any portion of this text or attachment(s), by credit card or charge card, that you permanently and irrevocably waive any and all right to cause a “chargeback” (that is, a disputed, reversed or contested charge) against this purchase for any reason whatsoever against the author or other reseller of this license, effective as soon as you receive registration code(s) from the author, open the envelope containing the program disk or otherwise install or use any attachment(s). You agree that, if you institute such a “chargeback”, it constitutes a material violation of this license, and damages the author in ways impossible to calculate, and with long-term adverse effects to the author. Therefore, you agree to pay, and author agrees to accept in compromise, for each chargeback you may issue or directly or indirectly cause to be issued against the author, the amount of EIGHT THOUSAND DOLLARS ($8,000.00) to the author (or the party selling you this license), as liquidated damages and not as a penalty. You expressly confess, in the event of such a “chargeback”, that such chargeback constitutes fraud and confess such fraud. You agree to pay all costs incurred by the author or the seller of this license in collecting these amounts.

The author reserves the right, at any time and from time to time, to update, revise, supplement, and otherwise modify this Agreement and to impose new or additional rules, policies, terms, or conditions on your use of the email or attachment(s) being distributed. Such updates, revisions, supplements, modifications, and additional rules, policies, terms, and conditions (collectively referred to in this Agreement as “Additional Terms”) will be effective immediately and incorporated into this Agreement. Your continued reading of any portion of this email will be deemed to constitute your acceptance of any and all such Additional Terms. All Additional Terms are hereby incorporated into this Agreement by this reference.

Nothing herein should be construed as constituting any kind of warranty. Should the author be found at fault for any damage, it will only be for the maximum extent allowed by applicable law, even if any remedy fails of its essential purpose. You acknowledge and agree that in order to protect the integrity of certain third-party content, the author and/or his licensors may provide for software security-related updates that will be automatically downloaded and installed on, or to, your computer. Such security related updates may impair the software (and any other software on your computer which specifically depends on the software) including disabling your ability to copy and/or play “secure” content, i.e. content protected by digital rights management.

Damit sind garantiert jegliche rechtlichen Fragen geklärt. Äusserst chic auch, dass das Mail nur unmerklich grösser wird …

Was ich wirklich denke

Der Vollständigkeit halber sei hier auch noch mein Antwort-Mail an den Mitarbeiter abgedruckt:

Wenn Sie wirklich „confidential information“ versenden, sollten Sie diese mit PGP chiffrieren. Dies ist aus Sicht des Technikers die einzige Möglichkeit, vertrauliche Informationen ohne Einsichtnahme Dritter vom Absender zum Empfänger zu transportieren. Ich erachte solche Footer als Platzverschwendung.

Was andere denken

Ein anderer geistesgegenwärtiger Zeitgenosse nimmt in einem ausführlichen Artikel die Disclaimer-Manie auseinander.
