Mail: proxy_smtp_auth directive. The proxy_smtp_auth directive instructs nginx to authenticate users on backend via the AUTH command (using the PLAIN SASL mechanism), similar to what is normally done for IMAP and POP3. If xclient is enabled along with proxy_smtp_auth, the XCLIENT command won't try to send the LOGIN parameter.
