Zowonongeka kuchokera ku spam ndizodziwikiratu komanso zomveka: kuphatikiza pa chiwopsezo chachitetezo chazidziwitso chabizinesi, zimatengera malo pa hard drive ya seva, komanso zimachepetsa magwiridwe antchito akalowa mu "Inbox". Kulekanitsa maimelo osafunsidwa kuchokera kumakalata abizinesi si ntchito yophweka monga momwe zimawonekera poyang'ana koyamba. Chowonadi ndichakuti palibe yankho lomwe limatsimikizira kupambana kwa XNUMX% pakusefa maimelo osafunikira, ndipo kukhazikitsidwa molakwika kwa ma algorithms ozindikiritsa maimelo osafunika kungayambitse vuto lalikulu kubizinesi kuposa sipamu yokha.
Mu Zimbra Collaboration Suite, chitetezo cha anti-spam chimakhazikitsidwa pogwiritsa ntchito pulogalamu ya Amavis yogawidwa mwaufulu, yomwe imagwiritsa ntchito SPF, DKIM ndikuthandizira mindandanda yakuda, yoyera, ndi imvi.

Makamaka, mukhoza kuika chiwerengero cha mfundo zomwe kalatayo idzaonedwa kuti ndi yokayikitsa ndikutumizidwa ku chikwatu cha Spam, kapena mukhoza kuika chiwerengero cha mfundo zomwe kalatayo idzachotsedwa. Mwa kukhazikitsa fyuluta ya sipamu motere, kudzakhala kotheka kuthetsa nkhani ziwiri nthawi imodzi: choyamba, kupewa kudzaza malo ofunika a disk ndi makalata opanda pake opanda pake, ndipo kachiwiri, kuchepetsa chiwerengero cha makalata a bizinesi omwe anaphonya chifukwa cha fyuluta ya spam. .
Vuto lalikulu lomwe lingakhalepo kwa ogwiritsa ntchito a Zimbra aku Russia ndi kusapezeka kwa makina opangira ma antispam omwe amasefa sipamu wachilankhulo cha Chirasha m'bokosi. Chifukwa cha izi chagona kusowa kwa malamulo omangika a malemba a Cyrillic. Anzake aku Western akuthetsa nkhaniyi pochotsa zilembo zonse m'Chirasha mopanda malire. Zowonadi, ndizokayikitsa kuti aliyense wamalingaliro abwino komanso okumbukira bwino ayesa kuchita bizinesi ndi makampani aku Europe mu Russian. Komabe, ogwiritsa ntchito aku Russia sangathe kuchita izi. Vutoli litha kuthetsedwa pang'ono powonjezera , komabe, kufunika kwawo ndi kudalirika sikutsimikiziridwa.
Chifukwa cha kugawa kwake kwakukulu komanso kachidindo kotseguka, zina, kuphatikiza zamalonda, zothetsera chitetezo zitha kupangidwa mu Zimbra Collaboration Suite. Komabe, njira yabwino kwambiri ingakhale njira yoteteza chitetezo cha cyber pamtambo. Chitetezo chamtambo nthawi zambiri chimakonzedwa kumbali ya opereka chithandizo komanso mbali ya seva yakomweko. Chofunikira pakukhazikitsa ndikuti adilesi yakomweko yamakalata obwera imasinthidwa ndi adilesi ya seva yamtambo, pomwe zilembo zimasefedwa, ndiye kuti zilembo zomwe zadutsa macheke onse zimatumizidwa ku adilesi yabizinesi.
Dongosolo loterolo limalumikizidwa ndikungosintha adilesi ya IP ya seva ya POP3 pamakalata obwera mu rekodi ya MX ya seva ndi adilesi ya IP ya yankho lanu lamtambo. Mwanjira ina, ngati m'mbuyomu seva yapafupi ya MX imawoneka motere:
domain.com. MU MX 0 pop
domain.com. MU MX 10 pop
pop MU A 192.168.1.100
Kenako mutasintha adilesi ya IP ndi yomwe mwapatsidwa ndi wothandizira pamtambo (tiyeni tinene kuti 26.35.232.80), zolowera zisintha kukhala zotsatirazi:
domain.com. MU MX 0 pop

pop MU A 26.35.232.80
Komanso, pakukhazikitsa muakaunti yanu ya nsanja yamtambo, muyenera kufotokoza adilesi yomwe imelo yosasefedwa idzachokera, ndi adilesi yomwe maimelo osefedwa ayenera kutumizidwa. Pambuyo pa izi, kusefa kwamakalata anu kudzachitika pa ma seva a gulu lachitatu, lomwe lidzakhala ndi udindo woteteza maimelo omwe akubwera mubizinesi.
