You'll want to peruse and/or publish here, the router/transport set the log cites as utilised - R=google_router T=google_smtp And it might help to turn up logging to +all temporarily, so as to be sure you can 'see' if there is any greylisting, single-recipient/single per-connection limiting or other defer action showing itself. As it is not the 'default' remote-smtp router/transport, any anal - ysis would be guesswork until you/we have sight of what that bespoke router/tramsport is doing...or attempting to do..
