ispconfig DKIM and sparkpost DKIM validator

Hi,
Using Ispconfig3 3.1.15p3 with 2048 bit length DKIM. I have dkim dns TXT entry and dmarcanalyzerk says it is valid.
if I testing my dkim with dkim sparkpost tools
It says: Signature could not be verified
But
if I try my DKIM settings with mxtoolbox
it says all ok.
can you help me please ?

thank you:
kib

 

I mean
ping\@tools\.mxtoolbox\.com
check says it's valid

the sparkpost tool is:
tools\.sparkpost\.com\/dkim

 

maybe...
but this is a few days old problem,

I hope someone try "sparkpost" with her/his own ispconfig and dkim configuration

 

Super, thank you very much!
However I'm a little bit sad because I tried the sparkhost with one of my cpanel server, which test results was good.

And if I try my DKIM settings with dkimvalidator\.com

it says:

the last two 0.1 point is weird to me. May be releated with the sparkpost error?

 

no, just tested another domain which is on a cpanel server
if you test your domain (which is run under ispconfig3) with dkimvalidator\.com. You also got the last two 0.1 points?

 

weird, I've got

0.1 DKIM_INVALID DKIM or DK signature exists, but is not valid

I've messed up something :'(
but don't know what

 

external provider

 

yes exactly, from the dns record field. After that, I ran the mxtoolbox (ping\@tools\.mxtoolbox\.com) test which says everything is ok. My client called my attention to sparkpost. But you have this phenomenon too. it's reassuring
And then I saw these +0.1 points on dkimvalidator\.com . which is weird but maybe not so important ...

 

10/10

This rule is automatically applied if your email contains a DKIM signature but other positive rules will also be added if your DKIM signature is valid. See immediately below.
0.1 DKIM_VALID Message has at least one valid DKIM or DK signature

0.1 DKIM_VALID_AU Message has a valid DKIM or DK signature from author's domain

0.1 DKIM_VALID_EF Message has a valid DKIM or DK signature from envelope-from domain

I have the same problem as well. My ISPCONFIG is on Ubuntu server . Everything seems to be installed properly but my emails are going to SPAM folders on both Gmail and Outlook. I couldn't get 10/10 on mail-tester.com following is the output of the test. My DKIM signature is not valid, I need help to get this working. Thanks

-0.001HTML_MESSAGEHTML included in message
No worry, that's expected if you send HTML emails-0.001MIME_QP_LONG_LINEQuoted-printable line longer than 76 chars

0.001SPF_PASSSPF: sender matches SPF record
Great! Your SPF is valid

-0.01T_DKIM_INVALID. Your DKIM signature is not valid
Have a look at our DKIM test below to know why, this may be a false-positive
