It is based +on Eric Greens IMAP2bis Maildir driver. + +PLEASE NOTE that this driver has only been tested in the IMAP4rev1 daemon +before. It was just put into Pine 4.00, and it looks like it works, but it +has not been extensively tested. It has been running for 8 months in +production in our IMAP4 daemon though. + +PLEASE NOTE: + +This driver needs to store the UID's of the message in the file somehow. In +the earlier versions of this driver this was done by adding a new maildir +flag (the ,3 flag), however, this solution was not very good since most +other clients could not handle it. Thus I had to find another solution. In +this driver I use a pretty radical method. Any file in the maildir with the +execute bit set has its UID set in the mtime of the file. So you should not +edit the files in here, or in any otherway update the mtime, because then +the UID gets changed. Most clients should not do this, so I think this +solution is compatible with most other clients (if you find one that isn't, +let me know). If you for some reason have to edit a file in the Maildir, +delete the ".uidvalidity" file in the root of the Maildir (ie, the dir where +you find cur/ new/ and tmp/). Alternatively, edit maildir.c and define the +NO_UID_VALIDITY option, which will cause the Maildir to get set new UID's on +every start up. Note that if you are running IMAP and Netscape as a client, +you can't change the UID's, because Netscape do not support the UID validity +flag in the IMAP protocol. So use this with care. + +Please edit the maildir.c file in any case. There are 3 options you can +set yourself. The default configuration is not suitable for ISPs. If you are +an ISP, or system with many users, you might want to consider setting some +of the options different. + +Ohh, if there are problems compiling it, let me know, and please let me know +what you did to fix it. This thing was developed on Solaris (using both GCC +and SunCC, should work with both), but I haven't tried it on any other +platform. It is also known to compile cleanly on Linux RH5.1 + +CONFIGURATION +------------- + +There are a few configurable options. You find these at the top of the +maildir.c file (and it can be found in imap/src/osdep/unix if I'm not all +mistaken). Right now, two options are configurable. By default it is +configured for ISP use, something that you might want to change if you use +it at home. + +HOW TO USE +---------- + +Use it as any other c-client driver. There is some option you want to change +if you want all folders to be created as Maildirs (and I can't remember what +the option is from the top of my head). Read the pine documentation. + +CHANGES +------- + +Rel 4. Coredump problem fixed. In release 3 I decided to user the sparep + in the message cache so no patching of mail.h would be necessary, + however, PINE uses this pointer internally for other things, causing + coredumps when used with the Rel 3. patch. + +Rel 3. New way of storing UID's (compatible with ,2 clients). + Multiple inbox patches applied + +Rel 2. Pine 4 changes. + +Rel 1. Imap4rev 1 driver + +FINAL NOTES +----------- + +I'll try to maintain and release new versions as soon as I have time over, +which unfortunately does not happen very often in this business ;) + +You can (might) find newer versions of this driver at: + +http://www.freeit.com/mta/ + + +Regards, +Daniel Mattias Larsson + +e-mail: ml@techno.org +ph: +46-707-268785 +snail-mail: +Industrivagen 4 +SE-194 77 Upplands Vasby +SWEDEN diff -Nru imap-4.6.BETA/src/c-client/mail.h imap-4.6.BETA.local/src/c-client/mail.h --- imap-4.6.BETA/src/c-client/mail.h Wed Sep 8 11:00:58 1999 +++ imap-4.6.BETA.local/src/c-client/mail.h Mon Sep 13 18:34:15 1999 @@ -621,6 +621,7 @@ unsigned int spare2 : 1; /* second spare bit */ unsigned int spare3 : 1; /* third spare bit */ void *sparep; /* spare pointer */ + void *maildirp; /* for the Maildir driver */ unsigned long user_flags; /* user-assignable flags */ } MESSAGECACHE; diff -Nru imap-4.6.BETA/src/osdep/unix/Makefile imap-4.6.BETA.local/src/osdep/unix/Makefile --- imap-4.6.BETA/src/osdep/unix/Makefile Mon Aug 23 20:30:38 1999 +++ imap-4.6.BETA.local/src/osdep/unix/Makefile Mon Sep 13 18:35:10 1999 @@ -35,7 +35,7 @@ EXTRAAUTHENTICATORS= SPECIALAUTHENTICATORS= -EXTRADRIVERS=mbox +EXTRADRIVERS= PASSWDTYPE=std @@ -93,7 +93,7 @@ # Standard distribution build parameters DEFAULTAUTHENTICATORS=md5 $(SPECIALAUTHENTICATORS) log -DEFAULTDRIVERS=imap nntp pop3 mh mx mbx tenex mtx mmdf unix news phile +DEFAULTDRIVERS=maildir imap nntp pop3 mh mx mbx tenex mtx mmdf unix news phile # Normally no need to change any of these @@ -102,7 +102,7 @@ BINARIES=mail.o misc.o newsrc.o smanager.o osdep.o utf8.o siglocal.o \ dummy.o pseudo.o netmsg.o flstring.o fdstring.o \ rfc822.o nntp.o smtp.o imap4r1.o pop3.o \ - unix.o mbox.o mbx.o mmdf.o tenex.o mtx.o news.o phile.o mh.o mx.o + unix.o mbox.o mbx.o mmdf.o tenex.o mtx.o news.o phile.o mh.o mx.o maildir.o CFLAGS=$(BASECFLAGS) $(EXTRACFLAGS) MAKE=make MV=mv @@ -653,7 +653,7 @@ tenex.o: mail.h misc.h osdep.h tenex.h dummy.h unix.o: mail.h misc.h osdep.h unix.h pseudo.h dummy.h utf8.o: mail.h misc.h osdep.h utf8.h - +maildir.o: mail.h misc.h osdep.h maildir.h dummy.h # OS-dependent diff -Nru imap-4.6.BETA/src/osdep/unix/env_unix.c imap-4.6.BETA.local/src/osdep/unix/env_unix.c --- imap-4.6.BETA/src/osdep/unix/env_unix.c Mon Jun 14 23:13:25 1999 +++ imap-4.6.BETA.local/src/osdep/unix/env_unix.c Mon Sep 13 18:34:15 1999 @@ -70,7 +70,7 @@ /* default directory protection */ static long dir_protection = 0700; /* default lock file protection */ -static long lock_protection = 0666; +static long lock_protection = 0600; /* default ftp file protection */ static long ftp_protection = 0644; /* default public file protection */ @@ -626,7 +626,7 @@ { char tmp[MAILTMPLEN]; if (!sysInbox) { /* initialize if first time */ - sprintf (tmp,"%s/%s",MAILSPOOL,myusername ()); + sprintf (tmp,"%s/Mailbox",myhomedir()); sysInbox = cpystr (tmp); /* system inbox is from mail spool */ } return sysInbox; diff -Nru imap-4.6.BETA/src/osdep/unix/maildir.c imap-4.6.BETA.local/src/osdep/unix/maildir.c --- imap-4.6.BETA/src/osdep/unix/maildir.c Wed Dec 31 16:00:00 1969 +++ imap-4.6.BETA.local/src/osdep/unix/maildir.c Mon Sep 13 18:34:15 1999 @@ -0,0 +1,1229 @@ +/* + * Maildir Module for PINE 4.0x - fourth release, use with CARE! + * + * Author: Mattias Larsson + * + * Version: 21.07.98 + * + * Please read the README.maildir file before using this module! + * + * If you have any questions, please e-mail ml@techno.org + * + * Multiple inboxes patch by Dean Gaudet + * + * ================================================= + * + * Based on the IMAP2 maildir routines by: + * + * Author: Eric Green + * Bloodhounds International Inc. + * thrytis@imaxx.net + * + * Additional contributions from: + * Aidas Kasparas (kaspar@soften.ktu.lt) + * + * Date: 27 April 1997 + * Last Edited: 13 June 1997 + * + * Based (heavily) on mh.c and other c-client library files by Mark Crispin: + * + * Mark Crispin + * Networks and Distributed Computing + * Computing & Communications + * University of Washington + * Administration Building, AG-44 + * Seattle, WA 98195 + * Internet: MRC@CAC.Washington.EDU + * + * Copyright 1995 by the University of Washington + * + * Permission to use, copy, modify, and distribute this software and its + * documentation for any purpose and without fee is hereby granted, provided + * that the above copyright notice appears in all copies and that both the + * above copyright notice and this permission notice appear in supporting + * documentation, and that the name of the University of Washington not be + * used in advertising or publicity pertaining to distribution of the software + * without specific, written prior permission.
