Name
${rcpt_host}
Synopsis
All
envelope addresses (sender and recipient) are passed through the
parse
rule set 0 so that a delivery agent can be
selected. Upon receipt of the RCPT TO: address, a delivery agent is
selected by the RHS of the parse
rule set 0, which
defines a triple that contains three pieces of information for that
address:
$#delivery_agent $@ host $:address
The $@
portion of the triple contains the host to
which to connect for delivery. For example:
your.domain
Once that host is determined for the $@
part of
the delivery agent triple, it is copied to this
${rcpt_host}
macro. For some
local
delivery agents, this
${rcpt_host}
macro can be undefined (NULL).
${rcpt_host}
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 $&{rcpt_host}
,
not ${rcpt_host}
).
