I did some more digging around and found this is reproducible on multiple hosts running the same version of Dovecot/Pigeonhole/Postfix. The problem resurfaces on any host to an account with enabled Vacation/OOO response. The Vacation/OOO reply filter was created in Roundcubemail, but has been fine for years. One thing to note is in Dovecot 2.3.0 I did enable UTF8, but even if I disable UTF8 the issue remains. What I have discovered after digging around is..
- After a fresh postfix restart all expected processes are running without any postdrop process.

- During the problem where the logs are complaining about permission denied and sendmail exiting with signal 15 (caused by inbound email to an address with enabled Vacation notice filter) there is a running postdrop process and several expected processes are not running.

When the issue is not present, an email TO any address with a disabled Vacation/OOO response filter is processed with no issues and stored in the respective folder moved by an existing filter not related to Vacation/OOO. Expected processes are still running (no postdrop process which when running seems to be causing the problem)
When the issue is not present, an email TO an address with a enabled Vacation/OOO response filter is processed and stored in the Inbox, but an auto-response fails to send. The result are these errors with the permission denied being repeated every ~minute.

After the problem starts again with the errors shown in the logs a postdrop process stays running in the background. After a short while the number of postfix processes decreases.
If I kill the postdrop process then the logged errors stop and the expected processes all show up again.
I am running out of ideas on why this has suddenly surfaced.

I think I am getting closer. Investigated further and the issue first surfaced: Dec 26 07:54:49 lmtp: Error: postdrop: warning: mail_queue_enter: create file maildrop/600085.6655: Permission denied
#1 upgrade [2017-12-25 03:18] [ALPM] upgraded dovecot (2.2.33.2-2 -> 2.3.0-1) [2017-12-25 03:18] [ALPM] upgraded pigeonhole (0.4.21-1 -> 0.5.0-1)
#2 upgrade [2017-12-26 16:44] [ALPM] upgraded pigeonhole (0.5.0-1 -> 0.5.0-2)
According to the upgrade timestamps it looks like ever since going from pigeonhole 0.4.21 to 0.5.0 is when the issue first surfaced. Here is a recent debug I collected:

It still isn't really clear to me why this is going on.

An important bit I forgot to add was the actual Vacation sieve code.
require ["fileinto","vacation"]; # rule:[Auto-Response] if header :contains "to" "me@domain.email" { vacation :days 1 :addresses "me@domain.email" :subject "My Subject Line" :from "noreply@domain.email" text:

I don't think my very first post containing doveconf -n made it
through, so posting here again.
