For each message it is the same message with different identifiers. From mainlog: 2025-09-19 14:36:46 1uzcDs-**************** == u...@email.tld R=virtual_user_accept T=maildir_delivery defer (30): Read-only file system: failed to open tmp/1758292606.M642770P207808.servername.tld (10 tries) As mentioned in previous messages in the thread, the maildir folder is marked 777 at the moment because I'm trying to get to the "why"... and it still won't write when initially received. But manually retrying the message as root will write the file (and set the permissions, owner, and group as specified in the .conf file) Other executables that emply some form of impersonation to deliver messages in these folders (e.g, Dovecot inserting a sent message) work without issue. It's a head-scratcher (for me, at least)., No related enries in mainlog or paniclog. Nothing germane to the problem in system logs. As I continue to read through the documentation for 4.97, I will look to harden the configuration and remove root at delivery (e.g. deliver_drop_privilege) and tighten up the permissions to see if it will resolve the problem. I'll follow up to the list after I've had time to mess with it over the weekend.
