Name
NEWDB
Synopsis
The db(3) form of
database uses a single file and can be shared by different
architectures. If you intend to support aliasing in an efficient
manner, you should at least define this NEWDB (or the NDBM described
earlier) in your Build m4
file. The db(3) routines are used to look up
aliases and are the routines used by the User Database (See this section). They can also be used to declare
hash and btree type maps
(Section 23.2.2) with the K
configuration command.
The db(3) libraries have overcome many of the limitations of the earlier ndbm(3) libraries. If possible, you should get and install the db(3) libraries before you build sendmail (see Section 3.1.2 for a guide to downloading these libraries).
If you are running a precompiled sendmail
binary, you can use the -d0.1 debugging
command-line switch (-d0.1) to determine if
NEWDB support is included (if it appears in the list, support is
included).
