Proxmox-virksomheden er kendt for udviklingen af distributionen til implementering af infrastruktur til virtuelle servere, udgivelsen af distributionen . Proxmox Mail Gateway præsenteres som en klar løsning til hurtigt at oprette et system til kontrol af mailtrafik og beskyttelse af den interne mailserver.
Installations-ISO-billede til gratis download. Distributionens specifikke komponenter er under AGPLv3-licensen. For installation af opdateringer er der tilgængelige både en betalt Enterprise-repository og , der adskiller sig i niveauet for stabilisering af opdateringer. Systemkomponenten i distributionen er baseret på Debian 10 (Buster) pakkegrundlag og Linux 5.3 kerne. installation af Proxmox Mail Gateway-komponenter oven på allerede fungerende servere baseret på Debian 10.
Proxmox Mail Gateway fungerer som en proxyserver, der fungerer som en gateway mellem det eksterne netværk og den interne mailserver baseret på MS Exchange, Lotus Domino eller Postfix. Der er mulighed for at styre alle indkommende og udgående mailstrømme. Alle maillogs analyseres og er tilgængelige for analyse via webgrænsefladen. Der tilbydes både grafer til vurdering af den samlede dynamik samt forskellige rapporter og formularer til at få oplysninger om specifikke e-mails og leveringsstatus. Understøttelse af oprettelse af klyngekonfigurationer for at sikre høj tilgængelighed (ved at føre en synkroniseret backupserver, data synkroniseres via SSH-tunnel) eller belastningsudligning.
Der tilbydes et komplet sæt værktøjer til at sikre beskyttelse, spamfiltrering, phishing og virus. For at blokere skadelige vedhæftninger anvendes ClamAV og Google Safe Browsing-databasen, mens der tilbydes et komplekst sæt foranstaltninger baseret på SpamAssassin for at bekæmpe spam, herunder støtte til omvendt kontrol af afsenderen, SPF, DNSBL, grålister, et bayesiansk klassificeringssystem og blokering efter liste over spammer-URI.
For legitimate correspondence, a flexible filtering system is provided, allowing you to define email processing rules based on the domain, recipient/sender, time of receipt, and type of content. There is an option to manage all incoming and outgoing email streams. All correspondence logs are parsed and accessible for analysis through a web interface. Both graphs for assessing overall dynamics and various reports and forms for obtaining information on specific emails and delivery status are provided.
Vigtige :
- Support for generating DKIM (DomainKeys Identified Mail) digital signatures for outgoing emails has been added. A web interface is provided for configuring DKIM application, allowing it to be enabled only for specific domains.
- A new system for quarantining deleted attachments has been introduced, for example, after triggering a virus or malware check. Instead of deleting such attachments, they can now be deferred along with emails for subsequent analysis by the administrator.
- A web interface has been proposed for setting weights of various spam filtering criteria in SpamAssassin. Weight changes are possible at the level of individual rules, allowing the anti-spam system to be adapted to the specifics of the current environment. Moreover, rules that lead to false positives can be selectively disabled.
- An experimental filtering mode before the SMTP session has been added, which occurs prior to queuing the message ("Before Queue"). This mode is incompatible with the Tracking Center.
- The processing of settings and rules in clustered environments has been improved. The filtering engine is now informed about changed settings requiring configuration reload, which reduces the number of situations that require manual restarting of pmg-smtp-filter. Change notifications are transmitted during cluster synchronization.
- The distribution has been synchronized with the Debian 10.2 package base. The Linux kernel has been updated to version 5.3, taken from Ubuntu 19.10.
