Additional Equates for Delivery Agents From Version 8.12 of sendmail

The following table describes additional equates that you can use with the M delivery-agent definition command. The following syntax shows you how to append new equates or new arguments to the equates that already exist in the configuration file.

Magent-name, equate, equate, ...

The following example includes the new W= equate. This equate specifies the maximum time to wait for the mailer to return after all data has been sent.

Msmtp, P=[IPC], F=mDFMuX, S=11/31, R=21, E=\r\n, L=990, W=2m

When you modify the definition of a value for m4 configuration, use the syntax that is provided in the following example.

define(`SMTP_MAILER_MAXMSGS', `1000')

The preceding example places a limit of 1000 on the number of messages that are delivered per connection on an smtp mailer.

If you need to build a new file, refer to Changing the sendmail Configuration in Chapter 2, Administering Mail Services.

Note - Typically, you modify the equate definitions in the mailer directory only when you fine-tune.
