Beginning with V8.12, the
mail.local program uses the same code as
sendmail uses to look up user-mailbox
information. By default, mail.local uses the
pw mailbox database type, which uses the
passwd(5) file, to locate the
user's home directory as well as user and group IDs.
Although pw is the only mailbox database type
allowed as of V8.12, you can add other mailbox types. For example, if
you were to add an LDAP type,
you could then do the following:
FEATURE(`local_lmtp')
define(`LOCAL_MAILER_ARGS', `mail.local -l -D ldap')
See MailboxDatabase for a description of mailbox
databases and the MailboxDatabase option.
