<h3>Configuration Changes Needed When Using Maildir</h3>
|
|
|
|
<p>If you forward your mail from the SDF cluster using a forward as
|
|
described in the <a href="http://sdf.org/?tutorials/metaarray">MetaArray</a>
|
|
tutorial, you may have to update your mail client's configuration, as mbox
|
|
format is used there. If you use procmail, for example, .procmailrc
|
|
configuration will be slightly different. Lockfiles are not needed in
|
|
recipes (the trailing ':' after the zero), and directories are used as
|
|
destinations for mail. Some of the environment variables are different, as
|
|
well:</p>
|
|
|
|
<pre>
|
|
ORGMAIL=/meta/mail/USERNAME
|
|
MAILDIR=/meta/LETTER/USERNAME/Maildir
|
|
PATH=/usr/pkg/bin:/usr/local/bin:/usr/bin:/bin
|
|
|
|
:0
|
|
.inbox/
|
|
</pre>
|
|
|
|
<p>The above will send all mail by default to the directory
|
|
'~/Maildir/.inbox' (just replace USERNAME with your own user name and LETTER
|
|
with the first letter of your user name).
|
|
</p>
|
|
|
|
<p>Here is a .forward that works with procmail on the MetaArray:</p>
|
|
|
|
<pre>
|
|
"|exec /usr/pkg/bin/procmail -f-||exit 75 #USERNAME"
|
|
</pre>
|
|
|
|
<p>Again, replace USERNAME as appropriate.</p>
|
|
|
|
<p>If you use mutt, your .muttrc will need to be updated. Here is
|
|
a minimal maildir config you can incorporate into an
|
|
existing .muttrc. Note the two 'set spoolfile' lines -
|
|
the commented one will tell mutt to pull from your system mail spool,
|
|
however the next, uncommented one that references the '.inbox/'
|
|
directory will work with the .procmailrc snippet,
|
|
above. The '.Sent' and '.Drafts' folders are just standard
|
|
folder names that are compatible with most IMAP implementations, but if you
|
|
don't use IMAP they can be named anything.
|
|
</p>
|
|
|
|
<pre>
|
|
#set spoolfile="/meta/mail/USERNAME"
|
|
set spoolfile="~/Maildir/.inbox/"
|
|
set folder="~/Maildir/"
|
|
set mbox_type = Maildir
|
|
set mask="!^\\.[^.]"
|
|
set record="+.Sent"
|
|
set postponed="+.Drafts"
|
|
|
|
mailboxes `echo -n "+ "; find ~/Maildir -maxdepth 1 -type d -name ".*" -printf "+'%f' "`
|
|
macro index c "<change-folder>?<toggle-mailboxes>" "open a different folder"
|
|
macro pager c "<change-folder>?<toggle-mailboxes>" "open a different folder"
|
|
macro index C "<copy-message>?<toggle-mailboxes>" "copy a message to a mailbox"
|
|
macro index M "<save-message>?<toggle-mailboxes>" "move a message to a mailbox"
|
|
</pre>
|
|
|
|
<p>The changes to the mailboxes command and c/C/M macros allow mutt to work
|
|
with maildir folders, even if the folder names change at some point.</p>
|

<h3>Converting Mbox to Maildir</h3>
|
|
|
|
<p>If you want to convert your existing mbox-style mailboxes to maildir
|
|
format, you can use 'mbox2maildir' to do so. The syntax for using it is as
|
|
follows:<p>
|
|
|
|
<pre>
|
|
mbox2maildir [mbox file] [maildir directory]
|
|
</pre>
|
|
|
|
<p>The maildir directory will be created if it does not exist. As an
|
|
example, let's say I have copied the mbox file for the gopher mailing list
|
|
from iceland to ma, and copied it to ~/mail/gopher (where it is on
|
|
iceland). I would then run the following:</p>
|
|
|
|
<pre>
|
|
mbox2maildir ~/mail/gopher ~/Maildir/.lists.gopher
|
|
</pre>
|
|
|
|
<p>Once run (no errors should be displayed), you can verify the contents of
|
|
the new maildir directory:</p>
|
|
|
|
<pre>
|
|
slugmax@ma:~> ls -la ~/Maildir/.lists.gopher/
|
|
total 40
|
|
drwx------ 5 slugmax arpa 4096 May 14 14:16 .
|
|
drwx------ 5 slugmax arpa 4096 May 14 14:16 ..
|
|
drwx------ 2 slugmax arpa 24576 May 14 14:16 cur
|
|
drwx------ 2 slugmax arpa 4096 May 14 14:16 new
|
|
drwx------ 2 slugmax arpa 4096 May 14 14:16 tmp
|
|
slugmax@ma:~> ls -la ~/Maildir/.lists.gopher/cur/
|
|
total 3472
|
|
drwx------ 2 slugmax arpa 24576 May 14 14:16 .
|
|
drwx------ 5 slugmax arpa 4096 May 14 14:16 ..
|
|
-rw------- 1 slugmax arpa 3452 May 14 14:16 1337019395.6264.mbox:2,S
|
|
-rw------- 1 slugmax arpa 5131 May 14 14:16 1337019396.6264.mbox:2,S
|
|
-rw------- 1 slugmax arpa 4094 May 14 14:16 1337019397.6264.mbox:2,S
|
|
...
|
|
</pre>
|
|
|
|
<p>You can see that mbox2maildir has converted each message in the mbox file
|
|
to its own file and placed each in the maildir-standard 'cur'
|
|
sub-directory.</p>
|
|
|
|
<h3>Converting Maildir to Mbox</h3>
|
|
|
|
<p>As you might guess, converting maildir-format folders to mbox is done by
|
|
the 'maildir2mbox' utility. It operates using environment variables, not
|
|
command line options, so to be clear it might be best to specify them with
|
|
the command:</p>
|
|
|
|
<pre>
|
|
MAILDIR=~/Maildir/.lists.gopher/ MAIL=~/mail/gopher MAILTMP=~/tmp/foo maildir2mbox
|
|
</pre>
|
|
|
|
<p>Note that the file specified by MAILTMP and the one specified by MAIL
|
|
must be on the same filesystem. When this command is run, you should see the
|
|
~/mail/gopher mbox file in place:</p>
|
|
|
|
<pre>
|
|
slugmax@ma:~> ls -l ~/mail/gopher
|
|
-rw------- 1 slugmax arpa 2680127 May 14 14:34 /meta/s/slugmax/mail/gopher
|
|
slugmax@ma:~>
|
|
</pre>
