The authentication methods specified in the L and (L extension) and L directives, are automatically added to this list if the L directive is enabled. It makes sense to specify the extensions supported by the POP3 backends to which the clients are proxied (if these extensions are related to commands used after the authentication, when nginx transparently proxies the client connection to the backend). The current list of standardized extensions is published at L.
