Convert From Mbox To Maildir

Converting from mbox to Maildir

Introduction

This article describes how to convert from mbox to Maildir format. Maildirs have quite a few advantages over mbox format, especially when you have a lot of users with large mailboxes. Another big advantage is that with dovecot and Maildirs, users can create sub-folders.

These notes are specific to my situation. I wasn’t able to find a complete guide to doing this anywhere, so hopefully it’ll serve as a good guide to others. My system uses:

  • Debian GNU/Linux 3.1r2
  • dovecot (POP3 and IMAPS)
  • exim4 (exim4-daemon-heavy)
  • procmail (some users have a ~/.procmailrc and there’s [continued…]

Some Tips for Passwords and Logins

  • R : Root, user role
  • S : System Accounts

In general order of increasing security.

Do not send passwords in clear text over the network

[RSU]

All modern Unix and Linux systems ship with secure alternatives as default, and either no longer contain or require manual intervention to enable legacy protocols.

Where legacy applications demand use of insecure protocols, [continued…]

Start X

Starting a Window Manager

When the idea of a graphical system for Unix was first introduced, there was a basic (very basic) graphical screen, based on what some of you will recognise as xdm. That is all well and good, but for those of us that like the CLI (Command-Line Interface), you can use:

startx

to force a normal console-login to start your desired window-manager. Graphical login managers use the underlying configuration file:

~/.xsession

While startx uses:

~/.xinitrc

Although, if no ~/.xinitrc file is present, startx will read ~/.xsession quite happily.

Initially (unless you have added one to /etc/skel/), these [continued…]
