+ <H1>Maildir Support</H1>
+
+ This version of Alpine has been enhanced with Maildir support. This text is
+ intended to be a reference on its support.
+ <P>
+
+ A Maildir folder is a directory that contains three directories called
+ cur, tmp and new. A program that delivers mail (e.g. postfix) will put new
+ mail in the new directory. A program that reads mail will look for for old
+ messages in the cur directory, while it will look for new mail in the new
+ directory.
+ <P>
+
+ In order to use maildir support it is better to set your inbox-path to the
+ value &quot;#md/inbox&quot; (without quotes). This assumes that your mail
+ delivery agent is delivering new mail to ~/Maildir/new. If the directory
+ where new mail is being delivered is not called "Maildir", you can set the
+ name of the subdirectory of home where it is being delivered in the <A
+ HREF="h_config_maildir_location"><!--#echo var="VAR_maildir-location"--></A> configuration
+ variable. Most of the time you will not have to worry about the
+ <!--#echo var="VAR_maildirlocation"--> variable, because it will probably be set by your
+ administrator in the pine.conf configuration file.
+ <P>
+
+ One of the advantages of the Maildir support of this version of Alpine is
+ that you do not have to stop using folders in another styles (mbox, mbx,
+ etc.). This is desirable since the usage of a specific mail storage system
+ is a personal decision. Folders in the maildir format that are part of the
+ Mail collection will be recognized without any extra configuration of your
+ part. If your mail/ collection is located under the mail/ directory, then
+ creating a new maildir folder in this collection is done by pressing "A"
+ and entering the string "#driver.md/mail/newfolder". Observe that adding a
+ new folder as "newfolder" may not create such folder in maildir format.
+
+ <P>
+ If you would like to have all folders created in the maildir format by
+ default, you do so by adding a Maildir Collection. In order to convert
+ your current mail/ collection into a maildir collection, edit the
+ collection and change the path variable from &quot;mail/&quot; to
+ &quot;#md/mail&quot;. In a maildir collection folders of any other format
+ are ignored.
+
+ <P> Finally, This version also has
+ <A HREF="h_config_courier_list">support</A> for the Courier style file system
+ when a maildir collection is accessed locally.

+
+ In a maildir collection, a folder could be used as a directory to store
+ folders. In the Courier server if you create a folder, then a directory
+ with the same name is created. If you use this patch to access a
+ collection created by the Courier server, then the display of such
+ collection will look confusing. The best way to access a maildir
+ collection created by the Courier server is by using the &quot;#mc/&quot;
+ prefix instead of the &quot;#md/&quot; prefix. If you use this alternate
+ prefix, then this feature applies to you, otherwise you can safely ignore
+ the text that follows.
+ <P>
+ Depending on if you have enabled the option
+ <a href="h_config_separate_fold_dir_view"><!--#echo var="FEAT_separate-folder-and-directory-entries"--></a>
+ a folder may be listed as &quot;folder[.]&quot;, or as two entries in the
+ list by &quot;folder&quot; and &quot;folder.&quot;.
+ <P>
+ If this option is disabled, Pine will list local folders that are in Courier
+ style format, as &quot;folder&quot;, and those that are also directories as
+ &quot;folder[.]&quot;. This makes the default display cleaner.
+ <P>
+ If this feature is enabled then creating folders in a maildir collection
+ will create a directory with the same name. If this feature is disabled, then
+ a folder is considered a directory only if it contains subfolders, so you can
+ not create a directory with the same name as an exisiting folder unless
+ you create a subfolder of that folder first (e.g. if you have a folder
+ called &quot;foo&quot; simply add &quot;foo.bar&quot; directly. This will
+ create the directory &quot;foo&quot; and the subfolder &quot;bar&quot; of it).
+ <P>
+ Observe that this feature works only for maildir collections that are accessed
+ locally. If a collection is accessed remotely then this feature has no value,
+ as the report is created in a server, and Pine only reports what received
+ from the server in this case.

+
+ Maildir Driver for Alpine 1.0
+ By Eduardo Chappa <chappa@washington.edu>
+ http://staff.washington.edu/chappa/alpine/
+
+ ---------------------------------------
+ 1. General Information About This Patch
+ ---------------------------------------
+
+ This patch adds support for the maildir format to Alpine. We take the
+ approach that this patch is one more driver among the number of formats
+ supported by Alpine (more generally c-client). This approach differs from
+ older versions of similar patches, in that once a maildir patch was
+ applied, it was assumed that all your folders would be created in the
+ maildir format.
+
+ This patch does not assume that maildir is a preferred format, instead
+ puts maildir in equal footing with other formats (mbox, mbx, mix, etc),
+ and so a maildir folder in the mail/ collection is treated in the same way
+ as any other folder in any other format. In other words, just by reading
+ the name of a folder, or opening it, or doing any operation with it, you
+ can not know in which format the folder is.
+
+ This implies that if you want to add a folder in the maildir format to the
+ mail/ collection, then you must add by pressing "A" in the folder list
+ collection and enter "#driver.md/mail/name_maildir_folder".
+
+ If you only want to use maildir, however, you can do so too. In this case,
+ you must create a maildir collection. In that collection, only maildir
+ folders will be listed. If there is any folder in any other format, that
+ folder will be ignored. In another words, any folder listed there is in
+ maildir format and can be accessed through that collection, conversely,
+ any folder not listed there is not in maildir format and there is no way
+ to access it using this collection.
+
+ In order to create a maildir collection, you could press M S L, and "A" to
+ add a collection. Fill in the required fields as follows:
+
+ Nickname : Anything
+ Server :
+ Path : #md/relative/path/to/maildir/collection/
+ View :
+
+ For example, if "path" is set to "#md/mail/", then Alpine will look for your
+ maildir folders that are in ~/mail/.
+
+ The code in this patch is mostly based in code for the unix driver plus
+ some combinations of the mh, mbx and nntp drivers for the c-client
+ library. Those drivers were designed by Mark Crispin, and bugs in this
+ code are not his bugs, but my own.
+
+ I got all the specification for this patch from
+ http://cr.yp.to/proto/maildir.html. If you know of a place with a better
+ specification for maildir format please let me know. The method this patch
+ uses to create a unique filename for a message is one of the "old
+ fashioned" methods. I realize that this is old fashioned, but it is
+ portable, and portability is the main reason why I decided to use an old
+ fashioned method (most methods are not portable. See the word
+ "Unfortunately" in that document).
+
+ --------------
+ 2. Other Goals
+ --------------
+
+ It is intended that this code will work well with any application
+ written using the c-client library. Of paramount importance is to make the
+ associated imap server work well when the server accesses a folder in
+ Maildir format. The program mailutil should also work flawlessly with this
+ implemetation of the driver.
+
+ It is intended that this driver be fast and stable. We intend not to
+ patch Alpine to make this driver do its work, unless such patching is for
+ fixing bugs in Alpine or to pass parameters to the driver.
+
+ ------------------------------------------------------------------------
+ 3. What are the known bugs of this implementation of the Maildir driver?
+ ------------------------------------------------------------------------
+
+ I don't know any at this time. There have been bugs before, though, but
+ I try to fix bugs as soon as they are reported. A complete list of updates
+ for this patch, which includes bug fixes, improvements and addition of new
+ features can be found at
+
+ http://staff.washington.edu/chappa/alpine/updates/maildir.html
+
+ ----------
+ 4. On UIDs
+ ----------
+
+ This patch keeps uids in the name of the file that contains the message,
+ by adding a ",u=" string to the file name to save the uid of a message. A
+ file is kept between sessions to save information on the last uid assigned
+ and its time of validity. Only one session with writing access can write
+ uids, all others must wait for the other session to assign them. The
+ session assigning uids creates a ".uidtemp" file which other sessions must
+ not disturb.
+
+ Uid support appeared in Alpine 1.00 (snapshot 925), and is experimental,
+ please report any problems.
+
+ --------------------------------------------
+ 5. Configuring Alpine and Setting up a Maildir
+ --------------------------------------------
+
+ Once this approach was chosen, it implied the following:
+
+ * This patch assumes that your INBOX is located at "$HOME/Maildir".
+ This is a directory which should have three subdirectories "cur",
+ "tmp" and "new". Mail is delivered to 'new' and read from 'cur'. I
+ have added a configuration option "maildir-location" which can be
+ used to tell Alpine where your Maildir inbox is, in case your system
+ do not use the above directory (e.g. your system may use
+ "~/.maildir"). In this case define that variable to be the name of
+ the directory where your e-mail is being delivered (e.g.
+ ".maildir").
+
+ * If you want to use the above configuration as your inbox, you must
+ define your inbox-path as "#md/inbox" (no quotes). You can define
+ the inbox-path like above even if you have changed the
+ maildir-location variable. That's the whole point of that variable.
+
+ -----------------------------------
+ 6. What about Courier file systems?
+ -----------------------------------
+
+ In a courier file system all folders are subfolders of a root folder
+ called INBOX. Normally INBOX is located at ~/Maildir and subfolders are
+ "dot" directories in ~/Maildir. For example ~/Maildir/.Trash is a
+ subfolder of INBOX and is accessed with the nickname "INBOX.Trash".
+
+ You can not access folders in this way unless you preceed them with the
+ string "#mc/". The purpose of the string "#mc/" is to warn Alpine that a
+ collection in the Courier format is going to be accessed, so you can
+ SELECT a folder like "#mc/INBOX.Trash", but not "INBOX.Trash"
+
+ You can access a collection through a server, but if you want to access a
+ collection of folders created using the Courier server, you MUST edit your
+ ".pinerc" file and enter the definition of the collection as follows:
+
+ folder-collections="Anything you want" #mc/INBOX.[]
+
+ You can replace the string "#mc/INBOX." by something different, for example
+ "#mc/Courier/." will make Alpine search for your collection in ~/Courier.
+
+ You can not add this directly into Alpine because Alpine fails to accept this
+ value from its input, but it takes it correctly when it is added through
+ the ".pinerc" file.
+
+ You can access your inbox as "#mc/INBOX" or "#md/INBOX". Both definitions
+ point to the same place.
