I have a dovecot system running in my kubernetes cluster that i use to gateway some emails to imap that are in turn used by systems that poll for email. No people are involved.

Its been running for sometime on 2.3, i've now updated the base container to 2.4 and i have two problems, perhaps related, perhaps not. I'm assuming its related to my config changes for 2.4, but I'm kind of at my wits end.

The first issue: Sep 06 15:05:31 imap(support)<443><YIobSSM+MMoKIAIr>: Debug: open(/proc/self/io) failed: Permission denied (euid=1001(support) egid=1001(support) missing +r perm: /proc/self/io)

I am seeing errors like this. I can't figure why. I tried "doveadm force-resync -u support /home/support/Maildir/" and it returns no errors.

The 2nd error, again, perhaps related, the user doing the poll for new email doesn't see it (despite I see the email delivered to the 'new' dir, it doesn't get picked up and moved to 'cur').

Below is my config file. In /home/support/Maildir i have the new, cur, tmp etc.

There's no mention of 'INBOX', which i think my previous had (mail_location = maildir:/home/%u/Maildir:INBOX=/var/mail/%u/Maildir was previous)

Any advice? I'm not sure where to go from here.
