Postfix/main.cf/receive override options


 * parameter: receive_override_options
 * default: (empty)
 * versions: 2.1 and later

About
Enable or disable recipient validation, built-in content filtering, or address mapping. Typically, these are specified in as command-line arguments for the smtpd, qmqpd or daemons.

Specify zero or more of the following options. The options override settings and are either implemented by smtpd, qmqpd, or pickup themselves, or they are forwarded to the cleanup server.


 * no_unknown_recipient_checks: Do not try to reject unknown recipients (SMTP server only). This is typically specified AFTER an external content filter.
 * no_address_mappings:Disable canonical address mapping, virtual alias map expansion, address masquerading, and automatic BCC (blind carbon-copy) recipients. This is typically specified BEFORE an external content filter.
 * no_header_body_checks:Disable header/body_checks. This is typically specified AFTER an external content filter.
 * no_milters:Disable Milter (mail filter) applications. This is typically specified AFTER an external content filter.

Note: when the "BEFORE content filter" setting is specified in the main.cf file, specify the "AFTER content filter" receive_override_options setting in master.cf (and vice versa).

Examples

 * receive_override_options = no_unknown_recipient_checks, no_header_body_checks
 * receive_override_options = no_address_mappings
