NAME

SYNOPSIS

--cache-store cache_store ] [ --log-file log_file ] [ --debug ] [ --version ] [ -h ]
DESCRIPION
emailproxy is an Email OAuth 2.0 Proxy: it transparently adds OAuth 2.0 support to IMAP/POP/SMTP client
applications, scripts or any other email use-cases that don't support this authentication method.
COMMAND-LINE OPTIONS
appearance
--no-gui
start the proxy without a menu bar icon (note: account authorisation requests will fail unless a pre-
authorised --config-file is used, or you use --external-auth or --local-server-auth and monitor
log/terminal output)
authentication methods
--external-auth
handle authorisation externally: rather than intercepting redirect_uri, the proxy will wait for you
to paste the result into either its popup window (GUI mode) or the terminal (no-GUI mode; requires
prompt_toolkit)
--local-server-auth
handle authorisation by printing request URLs to the log and starting a local web server on demand to
receive responses
server, account and runtime configuration
--config-file config_file
the full path to the proxy's configuration file (optional; default: emailproxy.config in the same
directory as the proxy script)
--cache-store cache_store
the full path to a local file to use for credential caching (optional; default: save to --config-
file); alternatively, an external store such as a secrets manager can be used - see readme for
instructions and requirements
logging, debugging and help
--log-file log_file
the full path to a file where log output should be sent (optional; default log behaviour varies by
platform - see readme for details)
--debug
enable debug mode, sending all client<->proxy<->server communication to the proxy's log
--version
show the proxy's version string and exit
-h, --help
show this help message and exit
