+## 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.

+-# University of Washington IMAP toolkit
++## 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.
