linux - DKIM : Signature header exists but is not valid -

-

i have configured postfix spf , dkim emails marked spam.

here domain.db (i use bind9) :

... mail._domainkey in      txt     ( "v=dkim1; k=rsa; p=abcd" )

i verify :

host -t txt mail._domainkey.domain.com

i receive (ok) :

mail._domainkey.domain.com descriptive text "v=dkim1\; k=rsa\; " "p=abcd"

i've checked problem on email-tester.com, , 10/10, dkim seems correctly installed.

but when check content of email, see : 

... dkim:pass dkim:pass spf:pass ... x-spam-report:  * -0.0 no_relays informational: message not relayed via smtp * -0.0 no_received informational: message has no received headers *  0.0 t_dkim_invalid dkim-signature header exists not valid  x-spam-status: no, score=0.0 required=5.0 tests=no_received,no_relays, t_dkim_invalid autolearn=ham autolearn_force=no version=3.4.0

any idea ?

----- update -------

after adding in master.cf :

-o receive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_milters

here new email content :

... dkim:pass   (now there one: ok) spf:pass  ... x-spam-report:  * -1.0 all_trusted passed through trusted hosts via smtp  x-spam-status: no, score=-1.0 required=5.0 tests=all_trusted autolearn=ham autolearn_force=no version=3.4.0

which seems better, email still marked spam, grrr

here's what's going on spf record.

go link , change dns server `google public dns (8.8.8.8) 

https://www.unlocktheinbox.com/dnstools/spf/luckeo.fr/

the results of spf v=spf mx ip4:176.58.101.240 ~all

now change dns advantage (156.154.70.1)

the results of spf v=spf1 mx ip4:176.58.101.240 ~all

notice difference v=spf vs v=spf1

so dns hasn't propagated yet , depending on how receiving email server looks dns records you're running issues. wait 24 hours , if you're still having issues, reply back.

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
