Il progetto vSMTP sviluppa un nuovo server di posta (MTA), mirato a garantire elevate prestazioni e offrire flessibili possibilit\u00e0 di filtraggio e gestione del traffico. Il codice del progetto \u00e8 scritto in Rust e distribuito con licenza GPLv3. <\/p>\n

Secondo i risultati di testing pubblicati dagli sviluppatori, vSMTP \u00e8 dieci volte pi\u00f9 veloce rispetto ai MTA concorrenti. Ad esempio, vSMTP ha mostrato una capacit\u00e0 di elaborazione da 4 a 13 volte superiore rispetto a Postfix 3.6.4, quando si inviano messaggi di 100 KB con 4-16 sessioni simultanee impostate. Le alte prestazioni sono ottenute grazie all'architettura multi-threading, in cui vengono utilizzati canali asincroni per l'interazione tra i thread.

\"vSMTP<\/center> <\/p>\n

vSMTP si sviluppa con una primaria attenzione alla sicurezza, garantita da un intenso testing che combina test statici e dinamici, oltre all'uso del linguaggio Rust, che consente di evitare molti errori legati alla gestione della memoria, se utilizzato correttamente. I file di configurazione sono definiti nel formato TOML.

\"vSMTP<\/center> <\/p>\n

Una delle caratteristiche del progetto \u00e8 la presenza di un linguaggio integrato chiamato vSL per la scrittura di script di filtraggio delle email, che consente la creazione di regole molto flessibili per escludere contenuti indesiderati e gestire il traffico. Il linguaggio si basa su Rhai, un linguaggio tipizzato dinamicamente, che permette di incorporare codice in programmi Rust e offre una sintassi che ricorda una fusione tra JavaScript e Rust. Gli script forniscono un API per ispezionare e modificare i messaggi in arrivo, reindirizzare i messaggi e gestire la loro consegna a host locali e remoti. Negli script \u00e8 supportata la connessione a DBMS, l'esecuzione di comandi arbitrari e la messa in quarantena delle email. Oltre a vSL, per contrastare i messaggi indesiderati, vSMTP supporta anche SPF e filtri basati su liste di open relay. <\/p>\n

Tra i piani per il prossimo rilascio si segnala la possibilit\u00e0 di integrazione con database basati su SQL (attualmente i dati sugli indirizzi e gli host sono forniti in formato CSV) e supporto per meccanismi di autenticazione DANE (DNS-Based Authentication of Named Entities) e DMARC (Domain-based Message Authentication). Nelle versioni pi\u00f9 avanzate sono previsti meccanismi BIMI (Brand Indicators for Message Identification) e ARC (Authenticated Received Chain), integrazione con Redis, Memcached e LDAP, strumenti per la protezione da attacchi DDoS e bot SPAM, plugin per eseguire controlli in pacchetti antivirus (ClamAV, Sophos, ecc.).
