Projektet vSMTP utvecklar en ny e-postserver (MTA) som syftar till att s\u00e4kerst\u00e4lla h\u00f6g prestanda och erbjuda flexibla m\u00f6jligheter f\u00f6r filtrering och trafikhantering. Projektkoden \u00e4r skriven i Rust och distribueras under GPLv3-licensen. <\/p>\n

Enligt de resultat som publicerats av utvecklarna \u00e4r vSMTP tio g\u00e5nger snabbare \u00e4n konkurrerande MTA. Till exempel uppvisade vSMTP mellan 4 och 13 g\u00e5nger h\u00f6gre kapacitet \u00e4n Postfix 3.6.4 vid \u00f6verf\u00f6ring av meddelanden som var 100 KB stora och med 4-16 samtidiga sessioner. Den h\u00f6ga prestandan uppn\u00e5s genom anv\u00e4ndning av en flertr\u00e5dad arkitektur d\u00e4r asynkrona kanaler anv\u00e4nds f\u00f6r interprocesskommunikation.

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

vSMTP utvecklas med ett prim\u00e4rt fokus p\u00e5 att s\u00e4kerst\u00e4lla h\u00f6g s\u00e4kerhet, vilket uppn\u00e5s genom intensiv testning med statiska och dynamiska tester, samt genom anv\u00e4ndning av Rust, vilket g\u00f6r det m\u00f6jligt att undvika m\u00e5nga minnesrelaterade fel. Konfigurationsfiler definieras i TOML-format.

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

En s\u00e4rskild funktion i projektet \u00e4r den inbyggda vSL-spr\u00e5ket f\u00f6r att skriva skript f\u00f6r filtrering av e-post, vilket m\u00f6jligg\u00f6r skapandet av mycket flexibla regler f\u00f6r avskiljande av o\u00f6nskat inneh\u00e5ll och trafikhantering. Spr\u00e5ket \u00e4r baserat p\u00e5 Rhai, som anv\u00e4nder dynamisk typning och m\u00f6jligg\u00f6r inb\u00e4ddning av kod i program skrivna i Rust samt erbjuder ett syntaktiskt som liknar en blandning av JavaScript och Rust. Skripten ges ett API f\u00f6r att inspektera och modifiera inkommande meddelanden, omdirigera meddelanden och hantera deras leverans till lokala och fj\u00e4rrv\u00e4rdar. I skripten st\u00f6ds anslutning till databaser, k\u00f6rning av godtyckliga kommandon och placering av meddelanden i karant\u00e4n. Ut\u00f6ver vSL st\u00f6djer vSMTP \u00e4ven SPF och filter baserade p\u00e5 \u00f6ppna rel\u00e4listor f\u00f6r att bek\u00e4mpa skr\u00e4ppost. <\/p>\n

Bland de planer f\u00f6r den kommande versionen framh\u00e4vs m\u00f6jligheten till integration med SQL-baserade databaser (just nu anges data om adresser och v\u00e4rdar i CSV-format) och st\u00f6d f\u00f6r autentiseringsmekanismerna DANE (DNS-Based Authentication of Named Entities) och DMARC (Domain-based Message Authentication). I mer avl\u00e4gsna versioner planeras implementering av mekanismer f\u00f6r BIMI (Brand Indicators for Message Identification) och ARC (Authenticated Received Chain), m\u00f6jligheten till integration med Redis, Memcached och LDAP, verktyg f\u00f6r skydd mot DDoS och SPAM-botar, samt plugins f\u00f6r att organisera kontroller i antivirusprogram (ClamAV, Sophos m.fl.).
