Updated: 1 December 1998
imap-4.5 is a maintenace update, with minor bugfixes to imap-4.4 and
optional support for CRAM-MD5.
This version supports IMAP4rev1 (RFC 2060). There are major internal and
external changes from the IMAP2bis version (e.g. imap-3.6, distributed with
Pine 3.9x). It is extremely unlikely that a program written for the IMAP2bis
verion will build with this version without modifications. Drivers written
for the IMAP2bis version will definitely need to be rewritten.
Most notable operational changes from imap-3.x:
. SASL authentication is supported in the IMAP and POP3 servers, and in
the IMAP, POP3, and SMTP client code. There is no support for NNTP
SASL yet
. CRAM-MD5 is supported on UNIX. To enable CRAM-MD5, you must obtain a
copy of RSA's implementation of MD5 (global.h, md5.h, and md5.c) and
place these files on /usr/local/include/md5/, add "md5" to the
EXTRAAUTHENTICATORS list in the top-level Makefile, and rebuild.
For CRAM-MD5 support in the IMAP and POP3 servers, you must have an
/etc/cram-md5.pwd file. This file has one line for each user name
that can use CRAM-MD5, in form username, TAB, password. Yes, the
passwords must be plaintext, so this file should be kept very strongly
protected. All CRAM-MD5 users must also have /etc/passwd entries. It
is recommended that the CRAM-MD5 password not be the same as the
plaintext password.
. Kerberos V5 is supported through the GSSAPI on UNIX and NT. To enable
Kerberos V5 on UNIX, add "gss" to the EXTRAAUTHENTICATORS list in the
top-level Makefile and rebuild. You may also need to edit the GSSAPI
directory paths in the ../src/osdep/unix/Makefile.gss
. Kerberos V4 client-only contributed code is available as:
ftp://ftp.cac.washington.edu/mail/kerberos4-patches.tar.Z
This is a patchkit which must be applied to the IMAP toolkit according
to the instructions in the patchkit's README.
. The mbox driver is now enabled by default. If the file "mbox" exists on
the user's home directory and is in UNIX mailbox format, then when INBOX
is opened this file will be selected as INBOX instead of the mail spool
file. Messages will be automatically transferred from the mail spool file
into the mbox file
To disable this behavior, delete "mbox" from the EXTRADRIVERS list in the
top-level Makefile and rebuild
. IMAP4rev1 protocol is now supported. The UNIX format support now maintains
unique identifiers (UIDs) and keyword flags for each message, and keeps an
invisible message at the start of the file which contains the UID base
information and a list of assigned keywords. There is no way to disable
this behavior, since it would disable IMAP4rev1 support. This message may
show up if you access the mailbox as a file using older mail software (e.g.
Pine 3.9x). It is invisible with IMAP or POP access, or with access as a
file using Pine 4.0x.
. Support for additional mailbox formats
. No longer keeps entire mailbox in memory for UNIX format files
. Multilingual searching of the following charsets are supported:
US-ASCII, UTF-8, ISO-8859-1, ISO-8859-2, ISO-8859-3, ISO-8859-4,
ISO-8859-5, ISO-8859-6, ISO-8859-7, ISO-8859-8, ISO-8859-9,
ISO-8859-10, ISO-8859-13, ISO-8859-15,
ISO-2022-JP, ISO-2022-KR, ISO-2022-CN, ISO-2022-JP-1, ISO-2022-JP-2,
GB2312 (alias CN-GB), CN-GB-12345, BIG5 (alias CN-BIG5),
EUC-JP, EUC-KR, Shift_JIS,
KOI8-R, KOI8-U (alias KOI8-RU), TIS-620, VISCII.
All ISO-2022-?? charsets are treated identically, and support ASCII,
JIS Roman, hankaku katakana, ISO-8859-[1 - 10], TIS, GB 2312, JIS X 0208,
JIS X 0212, KSC 5601, and planes 1 and 2 of CNS 11643.
EUC-JP includes support for JIS X 0212 and hankaku katakana
. Fast sorting including IMAP server-based sort
. Fast ordered-subject threading including IMAP server-based threading
Most notable programmer/external changes from imap-3.x:
. Additional ports
. New directory orientation, no separate non-ANSI sources
. New local file formats mbx and mx
. The bezerk driver has been retired, and replaced with the new unix driver
which does not keep a snapshot in memory
. Many new added ports including NT (Win32 client, NT server)
. Many new data access functions
. Numerous interface changes; look at the .h files for details
. There are no known security problems in this version
. If you ignored the warnings and used the evil configuration file, its name
and contents have changed incompatibly
