Proiectul vSMTP dezvolt\u0103 un nou server de email (MTA), destinat asigur\u0103rii unei performan\u021be ridicate \u0219i oferirii de op\u021biuni flexibile pentru filtrarea \u0219i gestionarea traficului. Codul proiectului este scris \u00een limbajul Rust \u0219i este distribuit sub licen\u021ba GPLv3. <\/p>\n

Conform rezultatelor test\u0103rii publicate de dezvoltatori, vSMTP este de zece ori mai rapid dec\u00e2t competitorii s\u0103i MTA. De exemplu, vSMTP a ar\u0103tat o capacitate de procesare de 4-13 ori mai mare dec\u00e2t Postfix 3.6.4, la transmiterea mesajelor de 100 KB \u0219i cu 4-16 sesiuni simultane. \u00cenalt\u0103 performan\u021b\u0103 este ob\u021binut\u0103 prin aplicarea unei arhitecturi multi-threading, \u00een care interac\u021biunea \u00eentre fire se face prin canale asincrone.

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

vSMTP se dezvolt\u0103 cu o orientare ini\u021bial\u0103 \u00een asigurarea unei securit\u0103\u021bi ridicate, ceea ce este realizat prin teste intensive folosind teste statice \u0219i dinamice, precum \u0219i prin utilizarea limbajului Rust, care permite evitarea multor erori legate de gestionarea memoriei. Fi\u0219ierele de configurare sunt definite \u00een format TOML.

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

O caracteristic\u0103 a proiectului este \u0219i existen\u021ba limbajului \u00eencorporat vSL pentru scrierea de scripturi pentru filtrarea emailurilor, permi\u021b\u00e2nd crearea unor reguli foarte flexibile pentru blocarea con\u021binutului nedorit \u0219i gestionarea traficului. Limbajul se bazeaz\u0103 pe Rhai, care utilizeaz\u0103 tipizare dinamic\u0103, asigur\u00e2nd integrarea codului \u00een programele Rust \u0219i oferind o sintax\u0103 care aminte\u0219te de o combina\u021bie \u00eentre JavaScript \u0219i Rust. Scripturile dispun de un API pentru inspectarea \u0219i modificarea mesajelor primite, redirec\u021bionarea mesajelor \u0219i gestionarea livr\u0103rilor acestora c\u0103tre gazde locale \u0219i la distan\u021b\u0103. Scripturile suport\u0103 conexiuni la baze de date, executarea de comenzi arbitrare \u0219i plasarea emailurilor \u00een carantin\u0103. Pe l\u00e2ng\u0103 vSL, pentru combaterea mesajelor nedorite, vSMTP suport\u0103 de asemenea SPF \u0219i filtre bazate pe liste de relee deschise. <\/p>\n

Printre planurile pentru viitoarea versiune se remarc\u0103 posibilitatea integr\u0103rii cu baze de date SQL (\u00een prezent, datele despre adrese \u0219i gazde sunt specificate \u00een format CSV) \u0219i suport pentru mecanismele de autentificare DANE (DNS-Based Authentication of Named Entities) \u0219i DMARC (Domain-based Message Authentication). \u00cen versiunile mai \u00eendep\u0103rtate, se preconizeaz\u0103 implementarea mecanismelor BIMI (Brand Indicators for Message Identification) \u0219i ARC (Authenticated Received Chain), posibilitatea integr\u0103rii cu Redis, Memcached \u0219i LDAP, instrumente pentru protec\u021bia \u00eempotriva atacurilor DDoS \u0219i a bot-urilor SPAM, pluginuri pentru organizarea verific\u0103rilor \u00een pachetele antivirus (ClamAV, Sophos etc.).
