 Next, edit the `emailproxy.config` file to add configuration details for each email server and account that you want to use with the proxy.
 [Guidance and example account configurations](https://github.com/simonrob/email-oauth2-proxy/blob/main/emailproxy.config) are provided for Office 365, Gmail and several other providers, though you will need to insert your own client credentials for each one (see the [documentation below](https://github.com/simonrob/email-oauth2-proxy/#oauth-20-client-credentials)).
 You can remove details from the sample configuration file for services you don't use, or add additional ones for any other OAuth 2.0-authenticated IMAP/POP/SMTP servers you would like to use with the proxy.
