Emva konyaka wophuhliso, isebe elitsha elizinzileyo le-Postfix 3.6.0 mail server likhutshiwe kwaye kwangaxeshanye, inkxaso ye-Postfix 3.2 yesebe ekhululwe ekuqaleni kuka-2017 yabhengezwa.
Postfix enye yeeprojekthi ezimbalwa ezidibanisa ukhuseleko oluphezulu, ukuthembeka kunye nokusebenza kwangaxeshanye, ethe yaphunyezwa ngombulelo kuyilo olucingisiswe kakuhle kunye nomgaqo-nkqubo ongqongqo wokukhowuda nophicotho-zincwadi.
Iimpawu eziphambili ezintsha Postfix 3.6.0
Kule nguqulo intsha Ukuhlanjululwa kwereferensi kumagama athi "mhlophe" kunye "nomnyama" kuye kwenziwa, ibonwa ngabanye abantu njengocalulo ngokobuhlanga. Endaweni "yoluhlu olumhlophe" kunye "noluhlu olumnyama", ngoku kufuneka usebenzise la magama alandelayo "uluhlu lokuvumela" kunye "noluhlu lokukhanyela" (umzekelo, iiparamitha postscreen_allowlist_interfaces, postscreen_denylist_action y postscreen_dnsbl_allowlist_threshold). Utshintsho luchaphazela amaxwebhu, ukucwangciswa kwenkqubo ye-post-screen (i-firewall edibeneyo), kunye nokubonakaliswa kolwazi kwiilogi.
Ukugcina amagama amadala kwiirekhodi, iparameter « inikezelwerespectful_logging=no«, ekufuneka ichazwe kwi-main.cf kunye nokuhambelana noqwalaselo lwangaphambili lomboniso ongasemva nalo lugciniwe ukuhambelana ngasemva. Ifayile yoqwalaselo "master.cf" nayo ayitshintshanga okwangoku.
Ngakolunye uhlangothi, olunye utshintsho olubonakalayo yale nguqulo intsha yimowudi ye-compatibility_level=3.6, utshintsho olungagqibekanga lwenziwa ukusebenzisa i-SHA256 hash function endaweni ye-MD5.
Xa uqulunqa inguqu yangaphambili, i-MD5 iyaqhubeka isebenza kwi-parameter yezinga lokuhambelana, kodwa ukulungiselela ulungelelwaniso olunxulumene nokusetyenziswa kwe-hashes, apho i-algorithm ingachazwanga ngokucacileyo, isilumkiso siya kuboniswa kwilogi.
Isusiwe inkxaso yoguqulelo lokuthumela ngaphandle lweprotocol yotshintshiselwano olungundoqo lweDiffie-Hellman (ixabiso leparameter alihoywanga ngoku tlsproxy_tls_dh512_param_file) iingxaki ezenziwe lula ezinxulumene nokuchaza inkqubo yomqhubi engachanekanga kwi-master.cf.
Ukubona iimpazamo ezinjalo, inkonzo nganye yangaphakathi, kuquka i-postdrop, ngoku ibhengeza igama leprothokholi ngaphambi kokuqala utshintshiselwano lwedatha, kunye nenkqubo nganye yomxhasi, kuquka i-sendmail, iqinisekisa ukuba igama leprotocol elibhengeziweyo lihambelana nokwahlukana okuxhasiweyo.
Kwakhona Kugxininiswa ukuba uhlobo olutsha lwezabelo longezwa «local_login_sender_maps« kulawulo olubhetyebhetye kwisabelo sedilesi yemvulophu yomthumeli (egqithiselwe kumyalelo othi "MAIL FROM" ngexesha leseshoni ye-SMTP) kwiinkqubo zokuthumela kunye ne-postdrop. Umzekelo, ukuvumela abasebenzisi basekuhlaleni, ngaphandle kwengcambu kunye ne-postfix, ukukhankanya kuphela ukungena kwabo kwe-imeyile usebenzisa i-UID ukubiza igama elibophelelayo.
Ukungagqibeki kwe-DNS Sebenzisa i-API entsha exhasa imisonto emininzi (umsonto-ekhuselekileyo) ngokungagqibekanga. Ukuqokelela le API ingentla, kufuneka uchaze xa uqulunqamake makefiles CCARGS="-DNO_RES_NCALLS... «.
Yongeziweenable_threaded_bounces=yes»ukubuyisela izaziso zeengxaki zonikezelo, ukuhanjiswa kade okanye ukuhanjiswa kwesiqinisekiso kunye ne-ID yengxoxo efanayo (umxhasi weposi uya kubonisa isaziso kwintambo efanayo, kunye neminye imiyalezo yembalelwano).
Ngokungagqibekanga, i-database ye-/etc/services system ayisasetyenziswa ukumisela amanani ezibuko le-TCP ye-SMTP kunye ne-LMTP. Endaweni yoko, amanani ezibuko aqwalaselwe ngendlela eyaziwayo_tcp_ports iparamitha (ehlala ikho lmtp=24, smtp=25, smtps=submissions=465, submit=587). Kwimeko apho naziphi na iinkonzo ezilahlekileyo kwizaziwa_tcp_ports, /etc/services ziya kusetyenziswa.
Umgangatho wokuhambelana ("compatibility_level") uphakanyiselwe kwixabiso "3.6" (iparameter yatshintshwa kabini kwixesha elidlulileyo, ngaphandle kwe-3.6, ixabiso le-0 (engagqibekanga), i-1 kunye ne-2 zixhaswa).
Ukususela ngoku ukuya phambili, "compatibility_level" iya kutshintsha kwinombolo yoguqulelo apho utshintsho lwe-compatibility-breaking lwenziwa. Ukujonga amanqanaba okuhambelana, abaqhubi bothelekiso abahlukeneyo bongezwe kwi-main.cf kunye ne-master.cf, efana ne "<= level" kunye "
Okokugqibela kuyakhankanywa ukuba ngenxa yotshintsho kwiiprothokholi zangaphakathi esetyenziselwa unxibelelwano phakathi kwamacandelo e-Postfix, kuyimfuneko ukumisa umncedisi weposi ngomyalelo "postfix stop" ngaphambi kokuhlaziya.
Ukungaphumeleli ukwenza oko kunokubangela ukusilela nge-pickup, qmgr, verify, tlsproxy, kunye ne-postscreen iinkqubo, ezinokulibazisa ukuthumela ii-imeyile de i-Postfix iqaliswe kwakhona.
