chown(/var/dovecot/login/ipc-proxy

Can we remove/change this in the source? So we do not have to add the CAP_CHOWN with containers.

chown(/var/dovecot/login/ipc-proxy)

When run as root this has user dovenull, maybe this can be resolved by using a group dovenull?

bash-5.0# ls -arlt total 4 srw-rw-rw- 1 root root 0 Nov 21 22:27 pop3 srw-rw-rw- 1 root root 0 Nov 21 22:27 login srw------- 1 dovenull root 0 Nov 21 22:27 ipc-proxy srw-rw-rw- 1 root root 0 Nov 21 22:27 imap drwxr-xr-x 1 dovecot dovecot 4096 Nov 21 22:27 .. drwxr-x--- 1 root dovenull 60 Nov 21 22:27 .

Maybe this would work

srw-rw---- 1 root dovenull 0 Nov 21 22:27 ipc-proxy
