It is not easy to solve, since bounces are not sent by local(8), so
we would need new a queue-file with "owner-test" as the new sender,
but there is no secure mechanism to record a command as the recipient
in the queue file.
So it seems to me that this is more of a feature than a bug, and
the solution could be along the lines of:
aliases:
owner-test: test-bounce-reader
test: command-al...@indirect.invalid, u...@external-server
command-alias: /bin/false
master.cf:
lcl-clnup unix n - n - 0 cleanup
-o virtual_alias_maps=$local_valias_maps
local unix - n n - - local
-o cleanup_service_name=lcl-clnup
lcl-virtual:
#
# Only addressable via indirect delivery in local(8)
#
command-alias command-al...@localhost.invalid
command-al...@localhost.invalid command-al...@localhost.invalid
command-al...@indirect.invalid command-al...@localhost.invalid
virtual:
# Special virtual mappings for restricted aliases
#
# Only addressable via indirect delivery in local(8)
#
command-alias command-al...@restricted.invalid
command-al...@localhost.invalid command-al...@restricted.invalid
command-al...@indirect.invalid command-al...@restricted.invalid
# ... Regular virtual mappings below
transport:
# Note: not a local domain in the sense of $mydestination!
localhost.invalid local:localhost
restricted.invalid error:5.1.1 Mailbox unavailable
.invalid error:5.1.2 Invalid destination domain
main.cf:
indexed = ${default_database_type}:${config_directory}/
virtual_alias_maps = ${indexed}virtual
local_valias_maps = ${indexed}lcl-virtual, $virtual_alias_maps
transport_maps = ${indexed}transport
alias_database = ${indexed}aliases
alias_maps = $alias_database
