Changes to the Timeout Option (Solaris 8 System Administration Supplement)

Solaris 8 System Administration Supplement

Changes to the `Timeout` Option

The following table provides information about the changes to the Timeout option. Specifically, this sendmail option has some new keywords and a new value for ident. In the Solaris operating environment, you should not need to change the default values for the keywords that are listed in the table. However, if you choose to make a change, use the keyword=value syntax. The value is a time interval. Refer to the following examples.

O Timeout.keyword=value   # for the configuration file
-OTimeout.keyword=value   # for the command line
define(`m4_name', value) # for m4 configuration

Note –

To avoid security risks, sendmail relinquishes its root permissions when you set this option from the command line.
