11.4.2.6 The recipients= (r=) queue-group equate
The MaxRecipientsPerMessage option (?§24.9.73 on page 1050) sets the default limit
for the number of recipients allowed per envelope. If there are more recipients than
that limit in an envelope, sendmail will split the envelope into two or more envelopes,
each with the limit or fewer recipients. If the MaxRecipientsPerMessage option
is zero, no limit is imposed.
The r= queue-group equate allows you to override the default for each queue group.
If the default allows unlimited recipients, or a large limit, you can use a smaller setting
for your queue group. Or, if the default is too small, you can enlarge it. You use
the r= equate like this:
recipients=99 ?†? set the limit to 99 recipients
recipients=0 ?†? set unlimited recipients
recipients=-99 ?†? same as r=0
recipients=none ?†? same as r=0
Note that a zero or negative expression sets the limit to unlimited. A nonnumeric
expression, such as in the last line, also sets the limit to zero (unlimited).
11.4.2.7 The Runners= (R=) queue-group equate
The Runners= (R=) queue-group equate tells sendmail how many queue processors to
launcheachqueue-processing interval.
