Why I can not get email score 10/10 for my email?

[Tommyhara]

Why I am getting this error testing with mail-tester .com

and its alearing that:

Your DKIM signature is not valid

My score is just 6.7/10 and I can get it 10/10

I have already got _dmarc, spf, DKIM on my Directadmin

I have same problem on cPanel.

but on Plesk control panel, it is easy to get 10/10 with mail-tester for my email

What things would you suggest to check and fix this problem?

Thanks

The error says your DKIM signature is not valid. So you have to look there first.

If I do a test with my company email resided on a DA server I get a 10/10 score.

You did everything the helpfile said?

Or maybe you need to do the DNS record for DKIM different on DA and Cpanel then you do on Plesk.
I use these 2 in DNS:

_domainkey	TXT	"o=~"

and

x._domainkey	TXT	"v=DKIM1; k=rsa; p=M...etc

exactly like that with the underscores and dots.

Thanks Richard!

I found the reason, because I used SSL thus I pointed to extra IP address for DKIM on DNS settings and now i can verify it at 9/10 on mail-tester.

it is a bit strange because
I have not added .include_if_exists /etc/exim.dkim.conf to /etc/exim.conf
and I tried to find the file /etc/exim.dkim.conf but didn't see it there.

and these commands

cd /usr/local/directadmin
cp -f conf/directadmin.conf

I checked directadmin.conf and didn't see dkim=1 there but dkim is enabled on my server.

I have not added .include_if_exists /etc/exim.dkim.conf to /etc/exim.conf

This is not needed if you are using the spamblocker exim.conf 4.x (4.5.4 right now if I'm correct). It has an "if exist" setting by default.
So that might be the reason that you did not have to make that setting yourself.

However it is odd that you don't have the exim.dkim.conf, did you forget to do step 2?
