--- Comment #6 from yvon.lafaille@??? ---
I think that the best way to understand and solve the bug is to reproduce it by
yourself using the elements of configuration i give in my first message.
But, to make your comprehension easier, i copy here more debug lines :
routing this-address.does-not-exist@???
--------> test_route router <--------
local_part=this-address.does-not-exist domain=gmail.com
checking domains
calling test_route router
test_route router called for this-address.does-not-exist@???
domain = gmail.com
original list of hosts = "smtp-test.unilim.fr" options =
expanded list of hosts = "smtp-test.unilim.fr" options =
set transport remote_smtp
finding IP address for smtp-test.unilim.fr
doing DNS lookup
queued for remote_smtp transport: local_part = this-address.does-not-exist
domain = gmail.com
errors_to=NULL
domain_data=NULL localpart_data=NULL
routed by test_route router
envelope to: this-address.does-not-exist@???
transport: remote_smtp
