[exim] To have gmail as smarthost is not working

I try to have gmail as smarthost.

The rules in exim looks like the following

----

relay_host:
   debug_print = "R: Relaying host for for $domain"
   driver = manualroute
   domains = "${if exists{CONFDIR/relay_hosts}\
                    {lsearch;CONFDIR/relay_hosts}\
               fail}"
   same_domain_copy_routing = yes
   route_data = smtp.gmail.com::587
   transport = remote_smtp_smarthost

----

remote_smtp_smarthost:
   debug_print = "T: remote_smtp_smarthost for $local_part@$domain"
   driver = smtp
   hosts_try_auth = <; ${if exists{CONFDIR/passwd.client} \
         {\
         ${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$host_address}}\
         }\
         {} \
       }

----

And the file CONFDIR/passwd.client is the following

*.gmail.com:USER@???:PASS
*.google.com:USER@???:PASS

----

The exim log look: My data is changed to XXXXXXXXX

Further information are:

For information it will work 100% with swaks
