Hello, this weekend we migrated our iredmail 1.6.1 (PHP 5.0) in Centos 7 to a Rocky 8 (new VM)

We installed iredmail 1.6.7 PHP 8.0 (Since iredmail doesnt support install older versions) and migrate all the configuration files, dovecot, postfix, amasvid, iredapd, etc

after a long afternoon of debugging and bug fixing we found a bug that we were unable to fix and we need your help with this issue please.
