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 "#md/inbox" (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 "mail/" to + "#md/mail". 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. + + <P> + <UL> + <LI><A HREF="h_finding_help">Finding more information and requesting help</A> + </UL><P> + <End of help on this topic> + </BODY> + </HTML> ====== h_config_literal_sig ===== <HTML> <HEAD> *************** *** 31999,32004 **** --- 32095,32143 ---- <P> <End of help on this topic> </BODY> + </HTML> + ====== h_config_courier_list ===== + <HTML> + <HEAD> + <TITLE>FEATURE: <!--#echo var="FEAT_courier-folder-list"--></TITLE> + </HEAD> + <BODY> + <H1>FEATURE: <!--#echo var="FEAT_courier-folder-list"--></H1> + + In a maildir collection, a folder could be used as a directory to store + folders.

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. + + ---------- + 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 + does 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/Dovecot 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. Therefore, 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 setting 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. + + Last Updated May 28, 2011
