UW-IMAP 2007f – modernized build for current Linux systems

This repository contains a maintained, buildable version of UW-IMAP 2007f adapted for modern Linux toolchains (glibc ≥ 2.36, GCC ≥ 11, OpenSSL ≥ 3).

The original UW-IMAP source no longer builds cleanly on current distributions. This repository keeps the upstream code intact and applies a small, focused patchset to restore buildability without functional changes.

Scope

This repository provides:

Upstream UW-IMAP 2007f source
A minimal patchset for:
- utime() compatibility with modern glibc
- scandir() callback signature fixes
- Removal of deprecated gets()
- Missing standard header includes
A reproducible build process

Not included:

Distribution packaging
PHP / PECL bindings
Kerberos support (disabled by default)

Build dependencies (Debian 12 / 13)

The following packages are required to build UW-IMAP 2007f:

apt install \
  build-essential \
  autoconf \
  automake \
  libtool \
  pkg-config \
  libssl-dev \
  libpam0g-dev \
  libc6-dev \
  libcrypt-dev \
  bison \
  flex

Notes

libc-client-dev is no longer available on modern Debian releases. UW-IMAP must be built from source.

OpenSSL 3.x is supported via the included patchset. Kerberos support is disabled (--without-kerberos).

Bundled tools (mtest, mlock, dmail, tmail) are built but optional.

Patches

All local fixes are provided as a linear patch series:

patches/
 0001-Fix-utime-usage-for-modern-glibc.patch
 0002-Fix-scandir-callback-signatures.patch
 0003-Replace-gets-with-fgets.patch
 0004-Add-missing-headers-for-modern-toolchains.patch

Build

Example build without Kerberos:

make lnp SSLTYPE=unix.nopwd

Original README: University of Washington IMAP toolkit

This repository is a copy of the University of Washington IMAP toolkit (imap-2007f.tar.gz/MD5:2126fd125ea26b73b20f01fcd5940369) which has become unavailable from the documented FTP and mirror sites. Posted here for both posterity and because a number of packages require the library and source/headers which may not always be suitable from the OS package manager.

In my case it was to compile PHP7 with IMAP support and utilizing an alternative (newer) OpenSSL version. It was very difficult to find trustworthy already-patched sources for this purpose. This seems to be a common problem for many in the same situation.

imap tools and server, c-client/libc-client/uw-imap-devel

The sources have been incrementally patched with the following from the Fedora Package Sources for uw-imap[1]. See the patches directory in this repository for the contents.

1006_openssl1.1_autoverify.patch
imap-2004a-doc.patch
imap-2007e-authmd5.patch
imap-2007e-overflow.patch
imap-2007e-poll.patch
imap-2007e-shared.patch
imap-2007e-system_c_client.patch
imap-2007f-format-security.patch

                UNIX QUICK BUILD NOTES

These quick build notes assume that you have installed OpenSSL before
attempting to build this software, and that you do not have any non-default
configuration parameters.

If you need additional information in building this software with OpenSSL,
please refer to the docs/SSLBUILD file for more information.

If you intend to build this software with a non-default configuration
(including building a non-compliant server without SSL support), please
refer to the docs/BUILD file for more information.

1) Look in the top-level Makefile and find your system type code.  For example,
   modern versions of Linux will use either "slx", "lnp", or one of the
   lnp-variants (such as "lrh").

2) Type "make" followed by the system type, e.g. "make slx".

3) Install the POP2 daemon (ipopd/ipop2d), the POP3 daemon (ipopd/ipop3d), and
   the IMAP daemon (imapd/imapd) on a system directory of your choosing.

4) Update /etc/services to register the pop2 service on TCP port 109, the
   pop3 service on TCP port 110, and the imap service on TCP port 143.  Also
   update Yellow Pages/NIS/NetInfo/etc. if appropriate on your system.

5) Update /etc/inetd.conf (or install files on /etc/xinetd.d) to invoke the
   POP2, POP3, and IMAP daemons on their associated services.

6) If your system uses PAM authentication, be sure to set up /etc/pam.d/imap
   (*not* /etc/pam.d/imapd) and /etc/pam.d/pop (*not* /etc/pam.d/ipop3d or
   /etc/pam.d/pop3d or /etc/pam.d/popd or /etc/pam.d/pop3).

7) Unless you built your system without SSL support, you will need to set
   up SSL server certificates as described in docs/SSLBUILD.

6) That's all!

Read the file docs/BUILD and docs/SSLBUILD if you need more detailed
information and/or you don't understand these quick build instructions.

                 MISCELLANEOUS NOTES

     mtest has been run under UNIX, DOS, Windows, NT, Macintosh, TOPS-20, and
VMS.  It is a very primitive interface, however, and is suited mainly as a
model of how to write a main program for c-client.  You should take a look at
the source to figure out how to use it.  Briefly, it first asks for a mailbox
name (either a local file path or an IMAP mailbox in the form
"{hostname}mailbox") and then puts you in a command mode where "?" will give
you a list of commands.

     Pine is available separately on the FTP.CAC.Washington.EDU archives.

     The focus of development and support is for UNIX and Win32 (including
Windows 95/98/Millenium, Windows NT, and Windows 2000).  The other ports are
not frequently used or tested, and may be incomplete.
