Yesterday, I was idly fiddling with the old patch postfix “memcached lookup table” created by Omar Kilani . unfortunately, patches can only be used for old postfix distributions (2.1.x – Released 2005-04-01, 2.2.x – Released 2005-04-01).

I rewrote the patch (code was not modified) so it can be applied against last postfix-2.9-20110706 snapshot.
This patches required memcached and libmemcache .

I was successfully compiled it, but not test it yet whether it will work or not. so it’s not recommended for use on production servers.

$ wget ftp://ftp.porcupine.org/mirrors/postfix-release/experimental/postfix-2.9-20110706.tar.gz
$ tar xzf postfix-2.9-20110706.tar.gz
$ cd postfix-2.9-20110706

Postfix memcache patch can be download here:
[download#41]

Compile postfix source that has been patched with postfix memcached patch. It’s just an example when I compile on my machine. adjust to fit your system environment.

$ make tidy
$ make -f Makefile.init makefiles OPT="-O2 -pipe" DEBUG="" CCARGS="-DHAS_MEMCACHE -I/usr/include -DHAS_CDB -DSNAPSHOT -DHAS_PCRE -DHAS_MYSQL -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/lib64/sasl2 -I/usr/include/sasl/ -I/usr/include/mysql/ -DUSE_TLS -DHAS_SSL" AUXLIBS="-lcdb -L/usr/lib64/mysql -lmysqlclient -lmemcache -lz -lm -ldb -lpcre -lsasl2 -lssl -lcrypto"
$ make

After the compilation process is completed, tests whether the lookup table has been compiled or not by issuing this command:

$ bin/postconf -m
btree
cdb
cidr
environ
hash
internal
memcache
mysql
nis
pcre
proxy
regexp
static
tcp
texthash
unix
Last warning: This patch is not tested. I rewrote Omar Kilani memcache patches postfix just for fun. when I have a headache after fixing a corrupt SAN storage that I use to store the maildir. :mrgreen:
