${mail_addr}
Saved $: value for MAIL From: triple V8.10 and later
Upon receipt of the MAIL
From:
address, a delivery agent is
selected by the RHS of a parse
rule set 0 rule, which defines a
triple that contains three pieces of information for
that address:
$#delivery_agent $@ host $:address
The $
: portion of
the triple contains the address part of the
information with any commentary removed. For
example:
gw@wash.dc.gov
Once that address is determined for the $
: part of the triple,
that address is copied to this ${mail_addr}
macro.
${mail_addr}
is
transient. If it is defined in the configuration
file or in the command line, that definition can be
ignored by sendmail. Note that
a $&
prefix
is necessary when you reference this macro in rules
(that is, use $&{mail_addr}
, not ${mail_addr}
).
