IMAP是电子邮件客户端组件,

本文环境为Centos 64位 DirectAdmin

32 bit

yum install krb5-devel libc-client libc-client-devel -y
wget http://dave.t0xic.nl/tars/imapback-2004c1-x86.tar.gz
tar xzf imapback-2004c1-x86.tar.gz
cd imap-2004c1
./buildit
cd c-client
mkdir /usr/local/imap-2004c1/
mkdir /usr/local/imap-2004c1/lib
mkdir /usr/local/imap-2004c1/include
cp *.h /usr/local/imap-2004c1/include
cp *.c /usr/local/imap-2004c1/lib
cp c-client.a /usr/local/imap-2004c1/lib
ln -s /usr/local/imap-2004c1/c-client.a /usr/local/imap-2004c1/libc-client.a

64bit

yum install krb5-devel libc-client libc-client-devel -y
cd /usr/local/directadmin/custombuild
wget http://dave.t0xic.nl/tars/imapback-2004c1-x86_64.tar.gz
tar xzf imapback-2004c1-x86_64.tar.gz
cd imap-2004c1
./buildit
cd c-client
mkdir /usr/local/imap/
mkdir /usr/local/imap/lib
mkdir /usr/local/imap/include
cp *.h /usr/local/imap/include
cp *.c /usr/local/imap/lib
cp c-client.a /usr/local/imap/lib
ln -s /usr/local/imap/c-client.a /usr/local/imap/libc-client.a

然后添加编译php的参数 重新编译成一次 即可

--with-pic \
--with-imap=/usr/local/imap \
--with-imap-ssl=/usr/local/imap

最后测试
php -m | grep imap
