* fix(build): use Debian's Dovecot config layout with the CE packages The Dovecot CE repo ships a minimal config layout that DMS does not expect: no 15-lda.conf, 90-fts.conf or 20-pop3.conf, a 2.3-style 20-managesieve.conf, and a dovecot.conf without the commented protocols/listen lines or the local.conf include. The startup scripts then fail to enable LMTP, so Postfix cannot deliver to Dovecot, and a custom dovecot.cf is ignored. When DOVECOT_COMMUNITY_REPO=1, install the config files from Debian's own packages of the same release, as Debian's postinst does. Also tolerate the missing 90-fts-flatcurve.conf, which only Debian ships, as the build otherwise fails. * fix(build): install ssl-cert explicitly Dovecot and Postfix default to the snakeoil cert from the ssl-cert package. Debian's dovecot-core depends on ssl-cert, but the Dovecot CE package does not, so with DOVECOT_COMMUNITY_REPO=1 the cert is missing and Dovecot fails to start when no SSL_TYPE is set. * fix(dovecot): disable attachment detection keywords explicitly Dovecot 2.4.2 changed the default of mail_attachment_detection_options to add-flags for maildir and dbox. This per-driver default is applied even with dovecot_config_version = 2.4.0, so LMTP adds a $HasNoAttachment keyword and maildir stores new mail in cur/ instead of new/. Set it explicitly to keep the 2.4.0/2.4.1 behaviour. This is a no-op with Debian's Dovecot 2.4.1. * tests: make the letsencrypt doveconf check work with Dovecot 2.4.2+ Querying `doveconf ssl_server` prints nothing with Dovecot 2.4.5, and querying the full setting names prints empty values with 2.4.1. Use `doveconf -n -P`, which prints the same lines on both. * docs: add changelog entries for the Dovecot CE build fixes * docs: link the changelog entries to #4834 * fix(build): exclude the CE repo instead of matching deb.debian.org Matching the deb.debian.org host made builds behind a different Debian mirror (Artifactory, apt-cacher-ng, regional mirrors) fail to find the Debian version of dovecot-core. There are only two sources, so exclude repo.dovecot.org instead. * docs: describe the attachment detection setting as a deliberate choice Mail in cur/ without the S flag is still valid maildir and still unread, so the explicit empty value is for parity with the Debian build, not a bug fix. Say so in the config comment and the changelog, and mention how to enable the feature. --------- Co-authored-by: Georg Lauterbach <44545919+georglauterbach@users.noreply.github.com>
