services<\/strong><\/h3>\n\n\n<h4 class=\"wp-block-heading\"><strong>1. Thundermail : Propre service de messagerie bas\u00e9 sur l&#8217;open source<\/strong><\/h4>\n\n\n<p class=\"wp-block-paragraph\">L&#8217;une des nouvelles offres les plus excitantes est &#8220;Thundermail&#8221;, un service de messagerie propre bas\u00e9 sur le logiciel Stalwart. Il offre non seulement des fonctions de messagerie, mais aussi une gestion de calendrier et de contacts. Le service devrait \u00eatre accessible via les domaines <strong>thundermail.com<\/strong> ou <strong>tb.pro<\/strong>. Les utilisateurs int\u00e9ress\u00e9s peuvent d\u00e9j\u00e0 s&#8217;inscrire pour la phase b\u00eata.<\/p>\n\n\n<h4 class=\"wp-block-heading\"><strong>2. Thunderbird Appointment : un organisateur de rendez-vous open source<\/strong><\/h4>\n\n\n<p class=\"wp-block-paragraph\">Un autre point fort est &#8220;Thunderbird Appointment&#8221;. Ce service vise \u00e0 offrir un moyen simple de prendre des rendez-vous en permettant aux utilisateurs de partager leur disponibilit\u00e9 via un lien. Le service ressemble \u00e0 des outils comme Calendly, mais reste open source et accorde une importance particuli\u00e8re \u00e0 la protection des donn\u00e9es. Le code source est d\u00e9j\u00e0 disponible sous forme de d\u00e9p\u00f4t public.<\/p>\n\n\n<h4 class=\"wp-block-heading\"><strong>3. Thunderbird Send : partage de fichiers s\u00e9curis\u00e9 comme une r\u00e9\u00e9dition de Firefox Send<\/strong><\/h4>\n\n\n<p class=\"wp-block-paragraph\">Avec &#8220;Thunderbird Send&#8221;, Mozilla ram\u00e8ne une version r\u00e9vis\u00e9e de &#8220;Firefox Send&#8221;, qui avait \u00e9t\u00e9 arr\u00eat\u00e9 en 2020. Ce service permet d&#8217;envoyer des fichiers volumineux de mani\u00e8re s\u00e9curis\u00e9e et crypt\u00e9e. Le r\u00e9f\u00e9rentiel pour Thunderbird Send a d\u00e9j\u00e0 \u00e9t\u00e9 publi\u00e9, de sorte que les utilisateurs et les d\u00e9veloppeurs peuvent jeter un coup d&#8217;\u0153il \u00e0 la nouvelle version en avance.<\/p>\n\n\n<h4 class=\"wp-block-heading\"><strong>4. Thunderbird Assist : des fonctions bas\u00e9es sur l&#8217;IA pour plus de confort<\/strong><\/h4>\n\n\n<p class=\"wp-block-paragraph\">Une autre fonction que Thunderbird souhaite proposer \u00e0 l&#8217;avenir est &#8220;Thunderbird Assist&#8221;. Il s&#8217;agit d&#8217;un ensemble de fonctions bas\u00e9es sur l&#8217;IA qui facilitent la r\u00e9daction et la gestion des e-mails. Il est int\u00e9ressant de noter que Thunderbird coop\u00e8re avec Flower AI et utilise \u00e9galement l&#8217;infrastructure de cloud computing confidentielle de Nvidia. Les utilisateurs peuvent d\u00e9cider s&#8217;ils veulent utiliser les fonctions d&#8217;intelligence artificielle localement ou dans le cloud.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><strong>Financement et mod\u00e8le \u00e9conomique<\/strong><\/h3>\n\n\n<p class=\"wp-block-paragraph\">Les nouveaux services seront d&#8217;abord gratuits pour les membres actifs de la communaut\u00e9. Plus tard, il est pr\u00e9vu d&#8217;offrir des versions gratuites limit\u00e9es, tandis que les fonctions avanc\u00e9es seront payantes. Ce mod\u00e8le doit non seulement couvrir les frais d&#8217;exploitation, mais aussi emp\u00eacher les abus des services.<\/p>\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion : Thunderbird explore de nouvelles voies<\/strong><\/h3>\n\n\n<p class=\"wp-block-paragraph\">L&#8217;introduction de services Pro et d&#8217;une plateforme de messagerie propre marque une \u00e9tape importante pour Thunderbird. L&#8217;accent mis sur l&#8217;open-source, la protection des donn\u00e9es et le contr\u00f4le des utilisateurs rend l&#8217;offre particuli\u00e8rement attrayante pour les personnes qui attachent de l&#8217;importance \u00e0 l&#8217;ind\u00e9pendance vis-\u00e0-vis des grandes entreprises de technologie. Reste \u00e0 voir si Thunderbird pourra s&#8217;imposer \u00e0 long terme comme une alternative \u00e0 Gmail ou Microsoft 365 &#8211; le potentiel est en tout cas l\u00e0.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Plus d&#8217;informations sur les nouveaux services sont attendues dans les mois \u00e0 venir.<\/p>\n<div id=\"netgu-3762884913\" class=\"netgu-after-content netgu-entity-placement\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-6258556257245998\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-6258556257245998\" \ndata-ad-slot=\"4559785002\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({});
