Fuller logs attached. Thanks for your help, Timo. # Adam Okay. Here's my steps: 1) Install 2.2.5 into fresh i386 FreeBSD 10.3-RELEASE-p5 jail. 2) Built with the following settings: root@apnoea-builder:/usr/ports/mail/dovecot2 # make -V CONFIGURE_ARGS --localstatedir=/var --with-statedir=/var/db/dovecot --without-shadow --with-docs --with-ioloop=kqueue --with-notify=kqueue --without-libwrap --with-ssl=openssl --without-vpopmail --without-gssapi --without-cdb --without-ldap --without-mysql --without-pgsql --without-sqlite --without-icu --without-lucene --without-solr --without-textcat --prefix=/usr/local ${_LATE_CONFIGURE_ARGS} 3) Copied files into place and made following changes: root@apnoea-builder:/usr/ports/mail/dovecot2 # dovecot -n # 2.2.25 (7be1766): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.3-RELEASE-p5 i386 auth_debug = yes auth_verbose = yes log_path = /var/log/dovelog mail_debug = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } ssl = no userdb { driver = passwd } 4.
