aaPanel_Kern the problem is that after the upgrade all this happened, now I can't reinstall the mail server and the backup taken to other servers with the panel gives the same error. I can't figure out which domain is causing problems and how to remove it
in any case the problem is that the 3.5 rmspda version is incompatible with the version of centos stream 8 , debian 10 , but the same problem is also encountered with debian 11 .. so now the question arises which version to use for email to work ? or that it can modify the db to control the various domains in order to be able to put the mail online?
