Mailer Flags

Table B-3 presents a complete list of the flags you can set in the mailer description. These flags are set in the configuration file.

The m flag allows the mailer to batch a mail message to multiple users if they are all receiving mail on the same host. This can improve response time. It can cause problems if the mail cannot reach one of the users. This will generate an error, which will cause the mail to be resent, and can generate duplicate mail. Remove this flag from the configuration file if potential problems associated with duplicate mail are too great.

The n flag selects to not add a UNIX-style From line on the front of the message. This is already done by /usr/lib/mail.local, so it should not be necessary for the mailer to do this.
