Sendmail Installation and Operation Guide
SMM:08-85
-wversion
Set the LDAP API/protocol version to use. The default depends on the LDAP
client libraries in use. For example, -w 3 will cause sendmail to use LDAPv3
when communicating with the LDAP server.
The dbm map appends the strings ".pag" and ".dir" to the given filename; the hash and btree
maps append ".db". For example, the map specification
Kuucp dbm -o -N /etc/mail/uucpmap
specifies an optional map named "uucp" of class "dbm"; it always has null bytes at the end of every
string, and the data is located in /etc/mail/uucpmap.{dir,pag}.
The program makemap(8) can be used to build any of the three database-oriented maps. It
takes the following flags:
-f
Do not fold upper to lower case in the map.
-N
Include null bytes in keys.
-o
Append to an existing (old) file.
-r
Allow replacement of existing keys; normally, re-inserting an existing key is an
error.
-v
Print what is happening.
The sendmail daemon does not have to be restarted to read the new maps as long as you change
them in place; file locking is used so that the maps won't be read while they are being updated.
New classes can be added in the routine setupmaps in file conf.c.
5.10. Q -- Queue Group Declaration
In addition to the option QueueDirectory, queue groups can be declared that define a (group
of) queue directories under a common name. The syntax is as follows:
Qname
{, field=value }+
where name is the symbolic name of the queue group under which it can be referenced in various
places and the "field=value" pairs define attributes of the queue group. The name must only consist
of alphanumeric characters. Fields are:
Flags
Flags for this queue group.
Nice
The nice(2) increment for the queue group. This value must be greater or equal
zero.
Interval
The time between two queue runs.
Path
The queue directory of the group (required).
Runners
The number of parallel runners processing the queue. Note that F=f must be set if
this value is greater than one.
Jobs
The maximum number of jobs (messages delivered) per queue run.
recipients
The maximum number of recipients per envelope. Envelopes with more than this
number of recipients will be split into multiple envelopes in the same queue direc-
tory. The default value 0 means no limit.
Only the first character of the field name is checked.
By default, a queue group named mqueue is defined that uses the value of the QueueDirectory
option as path. Notice: all paths that are used for queue groups must be subdirectories of QueueDi-
rectory. Since they can be symbolic links, this isn't a real restriction, If QueueDirectory uses a
wildcard, then the directory one level up is considered the ``base'' directory which all other queue
directories must share. Please make sure that the queue directories do not overlap, e.g., do not spec-
