[SOLVED] DKIM not creating key pairs

Hi,

I'm using ISPConfig 3.1.2 running on Debian Jessie

I'm using Dovecot and the DKIM configuration is the following:
system > server config > mail > DKIM path > /var/lib/amavis/dkim
system > server config > mail > DKIM strength > 1024

The problem I have is that whenever I go to:
email > domain > mydomain.tld I click on DKIM and it shows the DKIM configuration for that domain (like the picture), but when I click on "Generate Key" it just does nothing. I've tried changing the selector for another string, but still does nothing, I can't save with DKIM enabled as it has not any private key written.

I've also tried to generate with openssl a key pair and upload it to /var/lib/amavis/dkim, and copying with ctrl+x ctrl +v in the DKIM Private Key, and then I'm able to save the domain config, but when I go to the DNS of the domain, no DKIM record has been created automatically. (I haven't tried further actions with the manually generated key, as I want to do everything from the control panel).




Thanks you so much

 

Check every error logs first.

 

I've looked all of them already and couldn't find any suspicious, which one do you want me to post?

I just press the button and nothing happens, I don't even think it's calling any function.

 

did you disabled the php-function exec?

 

Yes, I did...
That was the issue, I tried enabling the "exec" function and it worked.

I added the DKIM, and after 1 minute I ran the mail-tester.com test and it detected the DKIM so I got the 10 out 10 mark

Thanks you so much!
