Postfix and Linux
Warning: if you can't compile Postfix because the file "db.h"
isn't found, then you MUST install the Berkeley DB development
package (name: db???-devel-???) that matches your system library.
You can find out what is installed with the rpm command. For example:
$ rpm -qf /usr/lib/libdb.so
This means that you need to install db4-devel-4.3.29-2 (on
some systems, specify /lib/libdb.so in the rpm query).
DO NOT download some Berkeley DB version from the network.
Every Postfix program will dump core when it is built with a different
Berkeley DB version than the version that is used by the system
library routines. See the
DB_README file for further information.
