Thanks for all my friend. and thanks for Joe's proposal. Last message is too long. can not reply it. Actually, I lost mysql-devel pcre-devel packages So I reinstall centos with these packages, and down postfix-2.9.3 Use the command make ,Everything working. I'm so glad
[root@mail ~]# make -f Makefile.init makefiles \ CCARGS="-DUSE_SASL_AUTH -DUSE_CYRUS_SASL -DHAS_LDAP -DHAS_MYSQL -I/usr/include/mysql -I/usr/include/sasl" \ AUXLIBS="-L/usr/lib64/sasl2 -lsasl2 -L/usr/lib64/mysql -lmysqlclient -lz -lm -lldap -llber" Finally, postfix-2.9.3 system got support with pcre, mysql and ldap. Thank you for all my friend's time. TOM
