Postfix: sender-dependent SASL authentication — relay to multiple SMTP hosts, or relay to the same host but authenticate as different users (e.g., two Gmail accounts)

This is a sequel to "Postfix: relay to authenticated SMTP".

I would like to send mail from two different Gmail accounts using Postfix. Here is the relevant section in the Postfix documentation: Configuring Sender-Dependent SASL authentication.

As a concrete example, here's how to set up two Gmail accounts (only relevant sections of the config files are listed below):

/etc/postfix/main.cf:
    # sender-dependent sasl authentication
    smtp_sender_dependent_authentication = yes

sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relay

Example Nginx configuration for adding cross-origin resource sharing (CORS) support to reverse proxied APIs
#
# CORS header support
#
# One way to use this is by placing it into a file called "cors_support"
# under your Nginx configuration directory and placing the following
# statement inside your **location** block(s):
#
# include cors_support;
#
# As of Nginx 1.7.5, add_header supports an "always" parameter which
