\u00c4ntligen kan du leva utan skr\u00e4ppost. Detta \u00e4r i princip bara m\u00f6jligt med ett professionellt skyddssystem som analyserar e-postmeddelandena och anv\u00e4nder alla tillg\u00e4ngliga m\u00f6jligheter f\u00f6r att f\u00f6rhindra att din egen dom\u00e4n missbrukas f\u00f6r att skicka skr\u00e4ppost.<\/p>\n

Detta kan till exempel g\u00f6ras med en gateway f\u00f6r skr\u00e4ppostskydd.<\/p>\n

\u00c4nnu idag finns det m\u00e5nga leverant\u00f6rer som inte skyddar e-postmeddelanden fr\u00e5n sina kunddom\u00e4ner. I regel \u00e4r det bara dom\u00e4nens MX-post som st\u00e4lls in p\u00e5 servern s\u00e5 att kunden ocks\u00e5 kan ta emot e-post via dom\u00e4nen.<\/p>\n

Detta medf\u00f6r ett antal faror. Eftersom eMial-systemet kan manipuleras mycket l\u00e4tt. Det \u00e4r m\u00f6jligt att helt enkelt f\u00f6rfalska avs\u00e4ndarnamnet. Du kan skicka ett e-postmeddelande under vilket dom\u00e4nnamn som helst. Om dom\u00e4n\u00e4garen inte har skyddat sig mot detta kan n\u00e5gon annan skicka e-post i hans namn. I v\u00e4rsta fall returneras svaren till dom\u00e4n\u00e4garen.<\/p>\n

Det beh\u00f6ver inte vara s\u00e5. Med n\u00e5gra f\u00e5 klick \u00e4r dom\u00e4nen v\u00e4l skyddad fr\u00e5n s\u00e5dana saker.<\/p>\n

SPF-post<\/h2>\n

Das Ramverk f\u00f6r avs\u00e4ndarpolicy<\/strong> (SPF) \u00e4r en av de metoder som anv\u00e4nds f\u00f6r att skydda avs\u00e4ndardom\u00e4nen mot f\u00f6rfalskning. Namnserverns SPF-post autentiserar de e-postservrar som f\u00e5r skicka e-post fr\u00e5n den h\u00e4r dom\u00e4nen.<\/p>\n

F\u00f6r webhosting.de skulle det till exempel vara dessa e-postservrar som anges i TXT-posten:<\/p>\n

\"v=spf1 mx a:spamschutz.webhoster.de a:spamschutz2.webhoster.de a:spamschutz3.webhoster.de a:spamschutz4.webhoster.de -all\"<\/p>\n

H\u00e4rmed till\u00e5ts att A-posterna p\u00e5 servrarna spamschutz.webhoster.de etc. samt MX-posterna p\u00e5 sj\u00e4lva dom\u00e4nen \u00e4r godk\u00e4nda f\u00f6r s\u00e4ndning.<\/p>\n

Viktigt: En SPF-post definieras genom RFC 7208<\/a> har blivit f\u00f6r\u00e5ldrad. SPF-posten definieras helt enkelt som en TXT-post i dom\u00e4nen.<\/p>\n

Med hj\u00e4lp av -all<\/strong> Vi f\u00f6rbjuder s\u00e4ndning via andra servrar.<\/p>\n

En leverant\u00f6r som kontrollerar SPF-posten kommer d\u00e5 inte att acceptera e-postmeddelandet eller markera det som misst\u00e4nkt f\u00f6r skr\u00e4ppost.<\/p>\n

DKIM-post<\/h2>\n

F\u00f6r att kontrollera e-postavs\u00e4ndarens \u00e4kthet anv\u00e4nds ett identifieringsprotokoll som t.ex. Dom\u00e4nnycklar<\/strong> fr\u00e5n Yahoo kr\u00e4vs.<\/p>\n

Sj\u00e4lva e-postmeddelandet \u00e4r f\u00f6rsett med en digital signatur som mottagarens e-postserver kan verifiera med en offentlig nyckel som finns tillg\u00e4nglig i DNS.<\/p>\n

Det finns nu flera olika s\u00e4tt att definiera det hela. Detta kan g\u00f6ras antingen p\u00e5 servern. F\u00f6r Plesk<\/a> m\u00e5ste du installera ett skript som lagrar nyckeln lokalt eller s\u00e5 m\u00e5ste du anv\u00e4nda Plesks DNS-server.<\/p>\n

Om kontrollpanelen inte erbjuder detta alternativ kan du helt enkelt anv\u00e4nda en gateway f\u00f6r skr\u00e4ppostskydd. H\u00e4r kan du ocks\u00e5 direkt l\u00e4gga till en signatur till alla autentiserade utg\u00e5ende e-postmeddelanden.<\/p>\n

Om leverant\u00f6ren \u00e4r ISTORE webhoster.de<\/a>\u00a0Det g\u00e5r till s\u00e5 h\u00e4r:<\/p>\n

I Plesk-menyn v\u00e4ljer du helt enkelt r\u00e4tt dom\u00e4n och klickar p\u00e5 ISTORE till h\u00f6ger.<\/p>\n

Som vi kan se \u00e4r DKIM-posten nu tillg\u00e4nglig, men det visas att det \u00e4nnu inte finns n\u00e5gon DMARC-post. Naturligtvis vill vi \u00e4ndra detta omedelbart och helt enkelt skapa en l\u00e4mplig DMARC-post.<\/p>\n

L\u00e4gg till DMARC-post<\/h2>\n

En tredje skyddsmekanism f\u00f6r e-post.\u00a0Dom\u00e4nbaserad autentisering, rapportering och \u00f6verensst\u00e4mmelse av meddelanden<\/b> (DMARC<\/b>) System.<\/p>\n

Detta kompletterar de SPF- och DKIM-poster som redan har angetts. SPF anv\u00e4nds f\u00f6r att ange vilka e-postservrar som f\u00e5r skicka e-post fr\u00e5n dom\u00e4nen. DKIM verifierar att e-postmeddelandet kommer fr\u00e5n avs\u00e4ndaren. Med DMARC kan dom\u00e4n\u00e4garen nu ge rekommendationer till den mottagande servern om vad den ska g\u00f6ra med e-postmeddelandet om SPF eller DKIM \u00e4r felaktiga. I regel avvisas e-postmeddelandet.<\/p>\n

En trevlig bieffekt \u00e4r rapporteringen. Med posten kan du skapa en E-postadress<\/a> till vilken e-postserverns rapporter sedan skickas. Det \u00e4r vettigt att anv\u00e4nda en rapporteringstj\u00e4nst i detta sammanhang. Detta erbjuds till exempel ocks\u00e5 av mxtoolbox eller n\u00e5gon annan tj\u00e4nst. I h\u00e4ndelse av missbruk av e-postmeddelandet kan \u00e5tg\u00e4rder sedan vidtas mycket snabbt.<\/p>\n

DMARC-posten kan skapas med en DMARC-postgenerator.<\/p>\n

Om allt \u00e4r korrekt konfigurerat kan du st\u00e4lla in att e-postanv\u00e4ndningen ska avvisas.<\/p>\n

\"DMARC<\/a><\/p>\n

I det h\u00e4r f\u00f6rsta exemplet \u00e4r rekommendationen inst\u00e4lld p\u00e5 ingen i h\u00e4ndelse av ett SPF- eller DKIM-fel, s\u00e5 att endast rapportering sker. Eftersom vi alltid g\u00f6r allting r\u00e4tt, kan posten ocks\u00e5 st\u00e4llas in direkt till avvisa<\/strong> \u00e4ndras.<\/p>\n

Slutkontroll av dom\u00e4ninst\u00e4llningarna<\/h2>\n

Vi anv\u00e4nder mxtoolbox igen f\u00f6r att kontrollera posterna efter att ha optimerat inst\u00e4llningarna.<\/p>\n
