-All the conditions of a rule need to be true for the rule action to be executed. All conditions are optional, but there needs to be at least one condition, to prevent matching all messages. If you want to match all senders or all recipients, you can just use the @ character as condition because all email addresses will contain this character.

Spam filtering, verification of the [DKIM](https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail) signature and [SPF](https://en.wikipedia.org/wiki/Sender_Policy_Framework) authorization is a task of email servers, not of an email client. Servers generally have more memory and computing power, so they are much better suited to this task than battery-powered devices. Also, you'll want spam filtered for all your email clients, possibly including web email, not just one email client. Moreover, email servers have access to information, like the IP address, etc of the connecting server, which an email client has no access to.
-Spam filtering based on message headers might have been feasible, but unfortunately this technique is [patented by Microsoft](https://patents.google.com/patent/US7543076).
+Spam filtrering baseret på meddelelsesoverskrifter kunne have været mulig, men denne teknik er desværre [patenteret af Microsoft](https://patents.google.com/patent/US7543076).
-Of course you can report messages as spam with FairEmail, which will move the reported messages to the spam folder and train the spam filter of the provider, which is how it is supposed to work. This can be done automatically with [filter rules](#user-content-faq71) too. Blocking the sender will create a filter rule to automatically move future messages of the same sender into the spam folder.
+Selvfølgelig kan du rapportere beskeder som spam med FairEmail, som vil flytte de rapporterede meddelelser til spam mappe og træne spam filter af udbyderen, hvilket er, hvordan det skal fungere. Dette kan gøres automatisk med [filterregler](#user-content-faq71) også. Blokering af afsenderen vil oprette en filterregel for automatisk at flytte fremtidige breve fra samme afsender til spam mappen.
-Note that you should not delete spam messages, also not from the spam folder, because the email server uses the messages in the spam folder to "learn" what spam messages are.
+Bemærk at du ikke bør slette spam-beskeder, heller ikke fra spam-mappen, fordi e-mail-serveren bruger meddelelserne i spam-mappen til at "lære", hvad spam-beskeder er.
-If you receive a lot of spam messages in your inbox, the best you can do is to contact the email provider to ask if spam filtering can be improved.
+Hvis du modtager en masse spam-beskeder i din indbakke, det bedste, du kan gøre, er at kontakte e-mail-udbyder for at spørge, om spam filtrering kan forbedres.
-Also, FairEmail can show a small red warning flag when DKIM, SPF or [DMARC](https://en.wikipedia.org/wiki/DMARC) authentication failed on the receiving server. You can enable/disable [authentication verification](https://en.wikipedia.org/wiki/Email_authentication) in the display settings.
+FairEmail kan også vise et lille rødt advarselsflag når DKIM, SPF eller [DMARC](https://en.wikipedia.org/wiki/DMARC) godkendelse mislykkedes på modtagerserveren. Du kan aktivere/deaktivere [godkendelsesbekræftelse](https://en.wikipedia.org/wiki/Email_authentication) i indstillinger.
-FairEmail can show a warning flag too if the domain name of the (reply) email address of the sender does not define an MX record pointing to an email server. This can be enabled in the receive settings. Be aware that this will slow down synchronization of messages significantly.
+FairEmail kan også vise et advarselsflag hvis domænenavnet på afsenderens (svar) e- mail- adresse ikke definerer en MX- post, der peger på en e- mail- server. Dette kan aktiveres i modtagelsesindstillingerne. Vær opmærksom på, at dette vil bremse synkronisering af beskeder betydeligt.
-If legitimate messages are failing authentication, you should notify the sender because this will result in a high risk of messages ending up in the spam folder. Moreover, without proper authentication there is a risk the sender will be impersonated. The sender might use [this tool](https://www.mail-tester.com/) to check authentication and other things.
+Hvis legitime meddelelser ikke autentificeres, du bør underrette afsenderen, da dette vil resultere i en høj risiko for, at beskeder ender i spammappen. Desuden er der uden ordentlig godkendelse en risiko for, at afsenderen vil blive efterlignet. Afsenderen kan bruge [dette værktøj](https://www.mail-tester.com/) til at kontrollere godkendelse og andre ting.
**(93) Can you allow installation/data storage on external storage media (sdcard)?**
