From what I can find out, the postfix local delivery agent is not chroot and it communicates with the main postfix processes via shared directories and pipes.On Tue, May 14, 2024 at 07:36:17PM +0800, jeremy ardley wrote:Postfix is chrooted (usuallly) to /var/spool/postfixIf this is true, then how would a local delivery agent work? It needs write access to all users' inboxes, which are either in /var/mail or in users' home directories. I could imagine the Postfix SMTP sending/receiving and queue processing programs being chrooted, but the LDA probably isn't. Or at least not chrooted to /var/spool/postfix.
To debug the problem I suggest checking the chroot and non chroot processes and eliminate those that are not relevant to the seen error messages
