Name
$M
Synopsis
When you define MASQUERADE_AS using the
m4 configuration technique, you both enable
masquerading (Section 4.4.2) and assign the
masquerade-as hostname to this $M macro. Note that
defining $M will not enable masquerading. You must
use the MASQUERADE_AS m4 configuration command
to enable this service.
You should never use this macro directly because it might change in a future release of sendmail. Use the MASQUERADE_AS mc configuration macro instead.
