Nginx Alias Apache

Bonjour,

Voila je rencontre un petit problème ma config nginx

server {
        listen 80;
        server_name mail.domain.com;
        return 301 https://$host$request_uri;
}

server {
        listen 443 ssl;

        server_name mail.domain.com;

    ssl_certificate /etc/letsencrypt/live/mail.domain.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/mail.domain.com/privkey.pem;

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        ssl_dhparam /etc/ssl/certs/dhparam.pem;
        ssl_ciphers 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA';

        add_header Strict-Transport-Security max-age=15768000;

        root /usr/share/roundcubemail/;

        index index.php index.html index.htm;

        location ~ \.(htm|html|php)$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                # FastCGI TCP Socket
                # fastcgi_pass 127.0.0.1:9007;

                # FastCGI Unix Domain Socket
                fastcgi_pass unix:/var/run/php-fpm/www.socket;
                fastcgi_index index.php;
                include fastcgi_params;
                fastcgi_read_timeout 630;
                fastcgi_param HTTPS on;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

}

J'ai z-push qui ce situe dans /usr/share/z-push.
Z-push doit etre accessible via l'url suivante: mail.domain.com/Microsoft-Server-ActiveSync

Comment dois-je faire?

Actuellement j'ai une installation apache ou j'ai configuré ca ainsi:

RewriteEngine On
    RewriteRule ^/Microsoft-Server-ActiveSync$ /usr/share/z-push/index.php
    <Directory /usr/share/z-push/>
        RewriteRule .* - [E=HTTP_MS_ASPROTOCOLVERSION:%{HTTP:Ms-Asprotocolversion}]
        RewriteRule .* - [E=HTTP_X_MS_POLICYKEY:%{HTTP:X-Ms-Policykey}]
        RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    </Directory>

Merci d'avance :)
