Proxmox, yomwe imadziwika kuti ipanga zida zogawa za Proxmox Virtual Environment poyika zida za seva, yatulutsa zida zogawa za Proxmox Mail Gateway 6.4. Proxmox Mail Gateway imaperekedwa ngati njira yosinthira mwachangu popanga dongosolo loyang'anira kuchuluka kwa maimelo ndikuteteza seva yamkati yamakalata.
Kuyika chithunzi cha ISO kulipo kuti mutsitse kwaulere. Magawo omwe amagawidwa ali ndi chilolezo pansi pa layisensi ya AGPLv3. Kuti muyike zosintha, malo onse olipidwa a Enterprise ndi nkhokwe ziwiri zaulere zilipo, zomwe zimasiyana mulingo wokhazikika. Gawo ladongosolo lagawidwe limakhazikitsidwa ndi phukusi la Debian 10.9 (Buster) ndi Linux 5.4 kernel. Ndizotheka kukhazikitsa zida za Proxmox Mail Gateway pamwamba pa ma seva omwe alipo a Debian 10.
Proxmox Mail Gateway imagwira ntchito ngati seva ya proxy yomwe imagwira ntchito ngati khomo pakati pa netiweki yakunja ndi seva yamkati yamakalata yotengera MS Exchange, Lotus Domino kapena Postfix. Ndizotheka kuyang'anira maimelo onse omwe akubwera ndi otuluka. Zolemba zonse zamakalata zimagawidwa ndipo zimapezeka kuti ziwunikidwe kudzera pa intaneti. Ma grafu onsewa amaperekedwa kuti awone momwe zimakhalira, komanso malipoti osiyanasiyana ndi mafomu kuti adziwe zambiri za zilembo zenizeni komanso momwe amaperekera. Imathandizira kupanga masinthidwe amagulu kuti apezeke kwambiri (kusunga seva yoyimilira yolumikizana, deta imalumikizidwa kudzera munjira ya SSH) kapena kusanja katundu.
Sefa yathunthu yachitetezo, spam, phishing ndi kusefa ma virus imaperekedwa. ClamAV ndi Google Safe Browsing amagwiritsidwa ntchito kuletsa zolumikizira zoyipa, ndipo njira zingapo zozikidwa pa SpamAssassin zimaperekedwa motsutsana ndi sipamu, kuphatikiza kuthandizira kutsimikizira kwa wotumiza, SPF, DNSBL, greylisting, Bayesian classification system ndi kutsekereza kutengera spam URIs. Pamakalata ovomerezeka, zosefera zosinthika zimaperekedwa zomwe zimakupatsani mwayi wofotokozera malamulo oyendetsera makalata kutengera dera, wolandila / wotumiza, nthawi yolandila ndi mtundu wazinthu.
Zatsopano zazikulu:
- Mawonekedwe a intaneti amaphatikiza chida chopangira ziphaso za TLS zamadomeni pogwiritsa ntchito Let's Encrypt service ndi protocol ya ACME, komanso kutsitsa ziphaso zopangidwa mnyumba.
- Dongosolo losefera sipamu la SpamAssassin lasinthidwa kuti litulutse 3.4.5 ndipo kuthekera kopereka zosintha zotsimikizika zamalamulo awonjezedwa.
- Kawonekedwe kabwino kakuwongolera mauthenga a spam okhala kwaokha. Mawonekedwe a administrator tsopano amatha kuwonetsa mauthenga onse omwe ali kwaokha.
- Kutha kuwona zambiri zamalumikizidwe otuluka omwe akhazikitsidwa pogwiritsa ntchito TLS awonjezedwa ku mawonekedwe owonera zipika.
- Kuphatikizana ndi zosungira zosunga zobwezeretsera zochokera ku Proxmox Backup Server zasinthidwa, ndipo kuthekera kolandila zidziwitso za imelo za zosunga zobwezeretsera kwawonjezeredwa.
