I think you are right.

So, something like:



I think you mainly want to define a new router that is higher priority
than the existing smarthost one  which goes to a new
transport which gets the password in a different way than passwd.client,
an example router:


gmailmarthost:
  debug_print = "R: smarthost for $local_part@$domain"
  driver = manualroute
  domains = ! +local_domains
  senders = my-gmail-address at gmail.com
  transport = my_smarthost_transport
  route_list = * mail.google.org::587 byname
  host_find_failed = ignore
  same_domain_copy_routing = yes
  no_more

I've probably got the host and port wrong above.
