+# Uncomment the following sections that are currently commented out
+# to enable building and packaging Sendmail executables and default
+# configuration files into the "sendmail" package.
+#
+# Note that in this edition of the "sendmail" package:
+#   1. No init script is provided to start the Sendmail daemon.
+#   2. The initial configuration files in /etc/mail are likely inadequate
+#      for running the Sendmail daemon on your LEDE/OpenWrt device.
+#   3. You may have to "opkg install m4" to build Sendmail configuration files
+#      from customized mc files on your LEDE/OpenWrt device using m4, or
+#      alternatively you may use a Linux computer to build configuration
+#      files from customized mc files.
+#   4. Compiling and building the "sendmail" package will likely fail at
+#      the packaging stage if you have already selected and built the "ssmtp"
+#      package. "ssmtp" installs /usr/sbin/sendmail in the form of a symlink
+#      to /usr/sbin/ssmtp. Where /usr/sbin/sendmail is already present,
+#      copying the sendmail executable into /usr/sbin/sendmail results in
+#      an error:
+#        cp: not writing through dangling symlink
+#        ...
+#        lede/source/include/toplevel.mk:206: recipe for target 'package/feeds/packages/libmilter/compile' failed
+#
+# ANYONE WHO IS READING THIS MAKEFILE AND WHO HAS THE KNOWLEDGE AND DESIRE
+# TO COMPLETE PORTING OF SENDMAIL TO LEDE/OPENWRT PLATFORM IS ENCOURAGED
+# TO DO SO AND TAKE OVER THE MAINTAINERSHIP OF THIS PACKAGE FROM VAL KULKOV.

@@ -0,0 +1,48 @@
+This patch increases the stack size for pthreads from 80 KB, the default
+stack size for musl libc, to 2 MB. The default stack size for glibc is 8 MB.
+
+OpenDKIM, an application that depends on libmilter, segfaults if the stack
+size for pthreads is left unchanged at the musl default value of 80 KB.
+Apparently, OpenDKIM allocates blocks of 64 KB multiple times, which causes
+libmilter and therefore OpenDKIM to crash:
+https://git.alpinelinux.org/cgit/aports/commit/?id=95724d1bd53ae87f72e6388cb7323dbd8f84be9d
