bye bye mbox, hello Maildir

Χρησιμοποιούσαμε Qpopper και mbox για Ν χρόνια (Ν=forever).
Χθες όμως ήταν η τελευταία μέρα.
Σήμερα χρησιμοποιούμε dovecot και Maildir.
Η αλλαγή στο mailbox format δεν έγινε «σ’ένα βράδυ».
Πήρε περίπου δύο μήνες.

Ηταν όμως το τελευταίο βήμα σε ένα έργο που δούλεψαν πολλοί άνθρωποι τα τελευταία 5 χρόνια.

Thank you all !

The 2009 ENISA Anti-Spam Measures Survey Report

The report of the 2009 ENISA Anti-spam Measures Survey is now available:

In 2009 ENISA launched an Anti-Spam Measures survey, asking e-mail service providers in Europe about the measures they take to combat spam in their networks. This survey provides a view of how the fight against spam has evolved since the last survey two years ago.

The survey aims to determine how e-mail service providers are combating spam on their networks. It helps identifying the state of the fight against spam and helps service providers to learn from their peers throughout Europe. Overall, we hope that this research will aid the industry’s understanding and development of best practices in the fight against spam.

Some of the key findings:

  • less than 5% of all email traffic is delivered to mailboxes;
  • most mail providers not only take care of protecting their customers from receiving spam, they also avoid sending spam to others;
  • fighting spam has reached maturity although continuous adaptation to new techniques is needed.

The survey report with detailed information about the measures is available for download.

Slides of the main survey results.

I would like to publicly congradulate ENISA on the methods they used to conduct this survey.

  • They sent a couple of preparatory emails asking if I would like to participate in such a survey and co-operate with a third party (asking for express permission to share my email address with another organization).
  • The actual survey, hosted on a dedicated site, had very easy to complete registration and clean/direct questions.
  • They sent a nice  «thank you for participating» email.
  • As soon as they processed the answers, they sent a preview of the results to the participants, including personalized answers! The preview report contained the survey’s key results and a custom comparison of my answers with the survey average. I didn’t have t remember my answers, they did it for me!

Well done ENISA people and thank you very much for your work!

dovecot

Ο dovecot είναι ένας πολύ ωραίος mail server (imap/pop3) που «κερδίζει έδαφος»..

Σύμφωνα με ένα mail του tss, η Mailtrust τον προσέλαβε full time για το 2009..

Πάγωσε το πανεπιστήμιο και μετακόμησε στις ΗΠΑ..

Το 2009 θα δούμε πιο γρήγηρο development στο dovecot λοιπόν..
