sendmail, 4th Edition

ErrorMode

Specify mode of error handling All versions

The sendmail program is flexible in its handling of delivery errors. By selecting from five possible modes with the ErrorMode option, you can tailor notification of delivery errors to suit many needs.

This option is intended primarily for use from the command line. If included in the configuration file, it should be given only a p or m argument, for print mode (the default) or mail-error mode.

The forms of the ErrorMode option are as follows:

O ErrorMode=mode                ← configuration file (V8.7 and later)
-OErrorMode=mode                ← command line (V8.7 and later)
define(`confERROR_MODE',mode)   ← mc configuration (V8.7 and later)
-emode                          ← command-line shorthand (not recommended)
Oemode                          ← configuration file (deprecated)
-oemode                         ← command line (deprecated)

The type of mode is a character. If mode is missing, the default value is p (for print normally). If this ErrorMode option is entirely missing, the default value is p.

The possible characters for the mode argument are listed in Table 24-20.
