Exim 4.96 mail server tau raug tso tawm, ntxiv cov kev txhim kho thiab ntxiv cov yam ntxwv tshiab. Raws li lub Tsib Hlis automated daim ntawv ntsuam xyuas ntawm kwv yees li 800 txhiab mail servers, qhov sib koom ntawm Exim yog 59.59% (ib xyoos dhau los 59.15%), Postfix yog siv 33.64% (33.76%) ntawm xa ntawv, Sendmail - 3.55% (3.55 %), MailEnable - 1.93% (2.02%), MDaemon - 0.45% (0.56%), Microsoft Exchange - 0.23% (0.30%).
Cov kev hloov loj:
- ACL siv qhov "pom" tshiab uas tuaj yeem siv los kuaj xyuas cov xwm txheej yav dhau los uas cuam tshuam rau cov neeg siv thiab cov tswv. Qhov xwm txheej tshiab ua rau nws yooj yim dua rau kev ua haujlwm nrog cov npe grey, piv txwv li, thaum tsim cov npe grey yooj yim, koj tuaj yeem siv ACL "pom = -5m / key=${sender_host_address}_$local_part@$domain" kom tso cai rau kev sib txuas. rov sim dua.
- Ntxiv "mask_n", qhov sib txawv ntawm "mask" tus neeg teb xov tooj uas tswj hwm qhov chaw nyob IPv6 ib txwm muaj (siv cov kab thiab tsis qhwv).
- Qhov kev xaiv '-z' tau ntxiv rau exim_dumpdb thiab exim_fixdb cov khoom siv kom rov qab sijhawm yam tsis tau suav rau hauv lub sijhawm thaj tsam (UTC);
- Ua raws li cov xwm txheej hauv keeb kwm yav dhau uas raug rho tawm haujlwm thaum TLS kev sib txuas ua tsis tiav.
- Ntxiv "stop", "pretrigger" thiab "trigger" xaiv rau ACL debug hom ("tswj = debug") los tswj cov zis rau lub cav debug.
- Ntxiv kev txheeb xyuas rau kev khiav tawm cov cim tshwj xeeb hauv cov lus nug nrhiav yog tias cov lus nug siv cov ntaub ntawv tau txais los ntawm sab nraud ("tainted"). Yog tias cov cim tsis tau dim, cov ntaub ntawv hais txog qhov teeb meem tam sim no tsuas yog cuam tshuam hauv lub cav, tab sis nyob rau hauv kev tso tawm yav tom ntej nws yuav ua rau muaj qhov yuam kev.
- Qhov kev xaiv "allow_insecure_tainted_data" tau raug tshem tawm, uas ua rau nws tuaj yeem cuam tshuam cov lus yuam kev thaum cov cim tshwj xeeb hauv cov ntaub ntawv tsis muaj kev nyab xeeb. Tsis tas li, kev txhawb nqa rau log_selector "taint" tau raug txiav tawm, uas tso cai rau koj los cuam tshuam cov lus ceeb toom ntawm kev khiav tawm cov teeb meem mus rau lub cav.
