the problem is default
 protocols = imap pop3 
packaging should use
protocols =
protocols = $protocols imap
etc.

Hello,

given a Debian 9 system with Dovecot 2.2.34 installed from self-built
packages made from the official tarball combined with Stephan Bosch's
debian files (upgraded multiple times from packages made in a similar way).
Today, I updated this system to 2.3.0.1 from the official repository at
repo.dovecot.org. After the update, dovecot wouldn't start because of:
> dovecot: master: Fatal: service(pop3) access(/usr/lib/dovecot/pop3)
failed: No such file or directory

Obviously, installing the dovecot-pop3d package, which provides the pop3
binary, made the error go away.
Nevertheless, until v. 2.2.34 not installing the pop3 binary had never
been a problem. Trying to solve this, I even commented the following
sections in the config (which previously hadn't caused problems since
the lines defining the ports etc. had already been commented):

> 10-master.conf:

> service pop3-login {
>   inet_listener pop3 {
>     #port = 110
>   }
>   inet_listener pop3s {
>     #port = 995
>     #ssl = yes
>   }
> }

> service pop3 {
>   # Max. number of POP3 processes (connections)
>   #process_limit = 1024
> }

> 10-director.conf:

> service pop3-login {
>   #executable = pop3-login director
> }

After those changes I had the configuration shown below, which produced
the described error.
Why would Dovecot insist that the pop3 binary has to exist on the system?

BTW: Note the protocols = line in the doveconf -n output, whereas

> # grep -R protocols /etc/dovecot/
> /etc/dovecot/dovecot.conf:# Most (but not all) settings can be overridden by different protocols and/or
