Hello,
due to some troubles I had to reinstall postfix and let I-MSCP reconfigure it. After that I had to do the same thing with opendkim because it seemed to be broken too (did uninstall using 'purge').
So I let the plugin create new dkim keys for my domain and set this entry also into the dns server. After checking it I saw, that the key attached is not the same as the key which I added in the dns server. Checking this using online dkim validator tools also told me it is not matching.
So my question now is:
How can I completely reset the plugin (and deleting everything) to do a clean new installation?
One thing: I recreated the key for my domain more than once and it was always the same key?!?
