See on suur kursuse algus, mis k\u00e4sitleb postiserverite t\u00f6\u00f6d. Minu eesm\u00e4rk ei ole kedagi kiiresti postiserveritega t\u00f6\u00f6le \u00f5petada. Siin on palju lisainfot, mis puudutab k\u00fcsimusi, millega me teel kokku puutume, kuna p\u00fc\u00fcan kursust luua peamiselt neile, kes teevad esimesi samme. <\/p>\n

\"Kuidas
\n<\/a><\/noindex>
\nEess\u00f5na<\/b>Nii juhtus, et t\u00f6\u00f6tan tasulise lektori ametis Linuxi haldamise valdkonnas. Koduseks \u00fclesandeks annan tudengitele k\u00fcmme linki erinevatele ressurssidele, kuna kuskil on materjali v\u00e4he, kuskil on see liiga keeruline. Erinevates ressurssides on materjal tihti dubleeritud ja m\u00f5nikord hakkab see ka lahknema. Samuti on enamus sisu ingliskeelne, ja m\u00f5nikord on tudengitel raskusi arusaamisega. Semajevi ja Lebedevi kursused on suurep\u00e4rased, ja v\u00f5ib-olla ka teised, kuid minu arvates on teatud teemad piisavalt v\u00e4he k\u00e4sitletud, samas kui m\u00f5ned ei seostu teistega piisavalt.<\/p>\n

Seet\u00f5ttu otsustasin \u00fchel p\u00e4eval materjali kokku v\u00f5tta ja anda seda \u00fcli\u00f5pilastele mugavas vormis. Aga kuna ma juba teen, miks mitte jagada seda k\u00f5igiga? Alguses p\u00fc\u00fcdsin teha teksti ja lisada sellele linke, kuid selliseid ressursse on miljoneid, mis siis kasu? M\u00f5nes kohas puudus visualiseerimine ja selgitused, m\u00f5nes kohas \u00fcli\u00f5pilased ei viitsi kogu teksti l\u00e4bi lugeda (ja mitte ainult nemad), mis toob kaasa teadmistega seotud l\u00fcngad.<\/p>\n

Aga asi ei ole ainult \u00fcli\u00f5pilastes. Kogu oma karj\u00e4\u00e4ri olen t\u00f6\u00f6tanud IT-integratsiooniettev\u00f5tetes, mis on tohutu kogemus erinevate s\u00fcsteemidega t\u00f6\u00f6tamiseks. L\u00f5puks sain laiap\u00f5hjalise inseneri. Sageli tuleb mul kokku puutuda IT- spetsialistidega erinevates ettev\u00f5tetes ja \u00fcsna sageli m\u00e4rkan, et neil on teadmiste l\u00f5ike. IT-sektoris on paljusid ised \u00f5ppijaid, sealhulgas mind. Ja mul on neid l\u00fcnki piisavalt, ning ma tahaksin aidata teisi ja end neist vabaneda.<\/p>\n

Minu arvates on l\u00fchikesed teabesalvestused palju huvitavamad ja kergemini omandatavad, seega otsustasin proovida seda formaati. Ja ma tean v\u00e4ga h\u00e4sti, et mu k\u00f5ne ei ole k\u00f5ige sujuvam, mind on keeruline kuulata, aga ma p\u00fc\u00fcan paremaks saada. See on minu jaoks uus hobi, mida tahaksin arendada. Varem oli mul kehvem mikrofon, praegu lahendan peamiselt heli ja k\u00f5nega seotud probleeme. Ma tahan teha kvaliteetset sisu ja vajan v\u00e4ga objektiivset kriitikat ja n\u00f5uandeid.<\/p>\n

P.S. M\u00f5ned on leidnud, et videovorming ei sobi ja parem on teha tekstina. Ma ei n\u00f5ustu t\u00e4iesti, aga olgu valideerimine \u2013 nii video kui ka tekst. <\/p>\n

\nJ\u00e4rgmine > Meiliserverite t\u00f6\u00f6re\u017eiimid<\/a><\/noindex><\/p>\n

Et saaksite t\u00f6\u00f6tada e-postiga, on teil vaja meiliprogrammi. See v\u00f5ib olla nii veebiklient, n\u00e4iteks gmail, owa, roundcube, kui ka arvuti rakendus \u2013 outlook, thunderbird jne. Oletame, et olete juba registreerunud m\u00f5nesse e-posti teenusesse ja peate oma meiliprogrammi seadistama. Avate programmi ja see k\u00fcsib teilt andmeid: konto nimi, teie e-posti aadress ja parool. <\/p>\n

\"Kuidas
\n
\nP\u00e4rast nende andmete sisestamist proovib teie postikliendi leida teavet teie postiserveri kohta. See toimub \u00fchenduse seadistamise lihtsustamiseks, kuna enamik kasutajaid ei tea serveri aadresse ja protokolle. Selleks kasutavad postikliendid erinevaid meetodeid serveri ja \u00fchenduse seadete teabe leidmiseks. Need meetodid v\u00f5ivad s\u00f5ltuda postikliendist. <\/p>\n

\"Kuidas
\n
\nN\u00e4iteks kasutab Outlook meetodit \u201eautodiscover\u201c, kus klient p\u00f6\u00f6rdub DNS-serveri poole ja k\u00fcsib teatud autodiscover-kande kohta, mis on seotud postidomaeniga, mille olete m\u00e4\u00e4ranud oma postikliendi seadetes. Kui administraator on selle kande DNS-serveris seadistanud, osutab see veebiserverile.<\/p>\n

\"Kuidas
\n
\nP\u00e4rast seda, kui post klient on saanud teada veebiserveri aadressi, p\u00f6\u00f6rdub ta selle poole ja leiab sealt eelnevalt ette valmistatud faili postiserveri \u00fchenduse seadistuste kohta XML-formaadis. <\/p>\n

\"Kuidas
\n
\nThunderbirdi puhul t\u00f6\u00f6tab meili klient ilma DNS autodiscoveri otsimiseta ja \u00fcritab otse \u00fchendust v\u00f5tta autoconfig veebiserveriga ja nimetatud domeeniga. Samuti proovib ta veebiserverist leida XML formaadis \u00fchenduse seadeid. <\/p>\n

\"Kuidas
\n
\nKui meili klient ei leia vajalike seadistustega faili, proovib ta \u00e4ra arvata seadeid levinud variantide seast. N\u00e4iteks kui domeen on example.com, kontrollib meili server, kas olemas on serverid imap.example.com ja smtp.example.com. Kui need leitakse, sisaldab seadeid see. Kui meili klient ei suuda kuidagi meili serveri aadressi m\u00e4\u00e4rata, palub ta kasutajal k\u00e4sitsi sisestada \u00fchenduse andmed. <\/p>\n

\"Kuidas
\n
\nSiis m\u00e4rkate 2 v\u00e4lju jaoks serverite<\/a> \u2014 sisendposti serveri aadress ja v\u00e4ljundposti serveri aadress. Reeglina on need v\u00e4ikeses organisatsioonis \u00fchesugused, isegi kui need on m\u00e4\u00e4ratud erinevate DNS-nimede kaudu, kuid suurtel ettev\u00f5tetel v\u00f5ivad need olla erinevad serverid. Kuid olgu tegemist sama serveriga v\u00f5i mitte \u2014 nende taga olevad teenused on erinevad. \u00dcks populaarsemaid posti teenuste kombinatsioone on Postfix & Dovecot. Postfix toimib v\u00e4ljundposti serverina (MTA \u2014 mail transfer agent), samas kui Dovecot on sisendposti server (MDA \u2014 mail delivery agent). Nimi \u00fctleb juba, et Postfix'i kasutatakse e-kirjade saatmiseks, Dovecot'i aga e-kirjade saamiseks e-posti kliendi kaudu. Posti serverid suhtlevad omavahel SMTP protokolli kaudu \u2014 st. Dovecot (MDA) on vajalik kasutajatele. <\/p>\n

\"Kuidas
\n
\nOletame, et oleme seadistanud \u00fchenduse oma posti serveriga. Proovime saata s\u00f5numi. S\u00f5numis anname oma aadressi ja saaja aadressi. N\u00fc\u00fcd, et s\u00f5num kohale toimetada, saadab teie e-posti klient s\u00f5numi teie v\u00e4ljundposti serverisse. <\/p>\n

\"Kuidas
\n
\nKui teie server saab s\u00f5numi, \u00fcritab ta leida, kellele see s\u00f5num toimetada. Teie server ei saa k\u00f5iki posti serverite aadresse peast teadma, seet\u00f5ttu p\u00f6\u00f6rdub ta DNS-i poole, et leida spetsiaalne MX-kirje, mis n\u00e4itab selle domeeni postiserverit. Need kirjed v\u00f5ivad erineda erinevate alamdomeenide jaoks. <\/p>\n

\"Kuidas
\n
\nP\u00e4rast seda, kui ta on tuvastanud saaja serveri aadressi, saadab ta teie s\u00f5numi selle aadressi kaudu SMTP-d, kus saaja posti server (MTA) v\u00f5tab s\u00f5numi vastu ja paneb selle spetsiaalsesse kataloogi, mida vaatab ka teenus, mis vastutab klientidele s\u00f5numite k\u00e4ttesaamise eest (MDA). <\/p>\n

\"Kuidas
\n
\nKui j\u00e4rgmine kord saaja posti klient k\u00fcsib sissetuleva posti serverilt uute s\u00f5numite olemasolu, saadab MDA talle teie s\u00f5numi. <\/p>\n

Kuna e-posti serverid t\u00f6\u00f6tavad internetis ja iga\u00fchel on v\u00f5imalus neile \u00fchenduda ning s\u00f5numeid saata, samuti on e-posti serverid laialdaselt kasutusel erinevate ettev\u00f5tete poolt oluliste andmete vahetamiseks, siis on see \u00fcsna ahvatlev sihtm\u00e4rk pahatahtlikuks tegevuseks, eriti r\u00e4mpsposti saatjatele. Seet\u00f5ttu on t\u00e4nap\u00e4evastes e-posti serverites palju t\u00e4iendavaid meetmeid saatja kinnitamiseks, r\u00e4mpsposti kontrollimiseks jne. Paljusid neist teemadest p\u00fc\u00fcan avada j\u00e4rgnevates osades.
