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.

* 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.

As you can see, Dovecot waits for it to finish for 30 seconds (override with submission_timeout setting). Can you try invoking sendmail manually from command line? Does it work? Is it hanging for more than 30s? Regards, Stephan.
