reverts commit bcfe0f0c1e9a2b91049d7c6c591c7f0c6a002c14 for now. It breaks most current use(r)s of the Dovecot service and needs to be combined with an extra modules configuration field of some kind. See <https://issues.guix.gnu.org/43347>.

2022-06-15	services: configuration: Use *unspecified* instead of 'disabled....Use *unspecified* as a marker for field values that have not been set. Rationale: 'disabled may easily clash with user values for boolean fields, is confusing (i.e. its meaning is *not* boolean false, but unspecified) and it also passes silently through the symbol? predicate of a field of type symbol. * gnu/services/configuration.scm (configuration-missing-default-value): Renamed from configuration-no-default-value. (define-maybe-helper): Use *unspecified* instead of 'disabled, and make the default value optional. * gnu/home/services/desktop.scm (home-redshift-configuration): Change (maybe-xyz 'disabled) to maybe-xyz. * gnu/services/authentication.scm (nslcd-configuration): Likewise. * gnu/services/cgit.scm (repository-cgit-configuration): Likewise. * gnu/services/file-sharing.scm (serialize-maybe-string) (serialize-maybe-file-object): Use 'unspecified?' instead of (eq? val 'disabled). * gnu/services/messaging.scm (raw-content?): Likewise.

(prosody-configuration): Likewise. * gnu/services/file-sharing.scm (transmission-daemon-configuration): Likewise. * gnu/services/messaging.scm (define-all-configurations): Use *unspecified* instead of 'disabled'. * gnu/services/networking.scm (opendht-configuration): Likewise. * gnu/services/pm.scm (tlp-configuration): Likewise. * gnu/services/telephony.scm (jami-account): Likewise.

2020-09-11	services: dovecot: Only serialize settings with non-empty values....* gnu/services/mail.scm (serialize-space-separated-string-list): Protocols might have custom settings, which are not supported by other protocols. To prevent dovecot/services from crashing, serialize settings that hold non-empty values only. Signed-off-by: Tobias Geerinckx-Rice <me@tobias.gr>	Alexey Abramov
2020-09-09	services: dovecot: Serialize global settings first....* gnu/services/mail.scm (dovecot-configuration): To avoid dovecot warning messages, move serialization of protocol settings below the global one. Signed-off-by: Tobias Geerinckx-Rice <me@tobias.gr>	Alexey Abramov
2020-09-09	services: dovecot: Use modules via symlink to system profile....* gnu/services/mail.scm (%dovecot-activation): Link the location with multiple plugins (dovecot-pigeonhole, etc), to a place where dovecot can find them. * gnu/services/mail.scm (dovecot-configuration): Use the symlink.

2020-04-21	services: dovecot: 'stop' method returns #f upon success....* gnu/services/mail.scm (dovecot-shepherd-service)[stop]: Use 'invoke' instead of 'make-forkexec-constructor'. Previously, the 'stop' method would return the PID of the "dovecot stop" process, which would be interpreted as a failure to stop the service.	Ludovic Courtès
2020-03-16	tests: opensmtpd: Check /var/spool/mail instead of /var/mail....The test had been failing since the upgrade to 6.6.3p1 in commit 2dbfd8eec43b602d23cee3fdd2842cc333e36c24. * gnu/services/mail.scm (opensmtpd-activation): Create /var/spool/mail. * gnu/tests/mail.scm (run-opensmtpd-test): Check /var/spool/mail instead of /var/mail.	Ludovic Courtès

2019-05-07	services: dovecot: Rename auth-verbose-passwords?....* gnu/services/mail.scm (dovecot-configuration)[auth-verbose-passwords?]: Rename to auth-verbose-passwords, and change the type to a string, as this parameter can take one of three string values. * doc/guix.texi (Dovecot service): Update the corresponding documentation.	Christopher Baines
2019-04-07	services: Add 'imap4d-service-type'....* gnu/services/mail.scm (<imap4d-configuration>): New record type. (imap4d-shepherd-service): New procedure. (%default-imap4d-config-file, imap4d-service-type): New variables. * gnu/services/mail.scm (Mail Services): Document it.	宋文武
