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 /etc/dovecot/dovecot.conf:# Enable installed protocols /etc/dovecot/dovecot.conf:!include_try /usr/share/dovecot/protocols.d/*.protocol /etc/dovecot/conf.d/20-managesieve.conf:#protocols = $protocols sieve /etc/dovecot/conf.d/10-ssl.conf:# SSL protocols to use /etc/dovecot/conf.d/10-ssl.conf:#ssl_protocols = !SSLv2
