You can get rid of the debug message with
import_environment = $import_environment PR_SET_DUMPABLE=2
or setting
sysctl fs.suid_dumpable=2

Hi, I've seen a few emails over the years related to this error message, but they are typically associated with doveadm. In my case, it's related to dovecot itself.
I've just set up dovecot-2.3.20-1.fc37.x86_64 on fedora37 and unable to receive mail. The main config was copied over from another dovecot system on fedora37 with virtually identical settings, including the same SSL cert. I've also tried to just migrate the important stuff and otherwise leave the defaults, but I'm having the same problem.

I've set the /var/spool/mail/bcc-user permissions to 600, bcc-user:mail. The /home/bcc-user directory is 611, bcc-user:bcc-user.
Here is my doveconf -n:

Any ideas greatly appreciated. I was very surprised to be having problems after having done this so many times before.
