Dovecot is an open source IMAP and POP3 email server for Linux/UNIX-like
systems, written with security primarily in mind. Dovecot is an excellent
choice for both small and large installations. It's fast, simple to set up,
requires no special administration and it uses very little memory.
Dovecot is high-performing, self-optimizing, self-healing, and easily
extensible. It includes IMAP4rev1 and POP3 support. IPv6, SSL and TLS are
supported. It supports multiple commonly used IMAP extensions, including SORT,
THREAD and IDLE.
===> The following configuration options are available for dovecot-2.3.21.1_3:
DOCS=on: Build and/or install documentation
EXAMPLES=on: Build and/or install examples
LIBSODIUM=off: Support libsodium based crypts (ARGON2I/ARGON2ID)
LIBUNWIND=off: Get backtraces using libunwind
LIBWRAP=on: TCP wrapper support
LUA=off: Lua scripting language support
LZ4=off: LZ4 compression support
====> Database support
CDB=off: CDB database support
LDAP=on: LDAP protocol support
MYSQL=off: MySQL database support
PGSQL=off: PostgreSQL database support
SQLITE=off: SQLite database support
====> Full text search plugins
ICU=off: Use libicu for FTS unicode normalization
LUCENE=off: CLucene FTS support
SOLR=off: Solr FTS support
TEXTCAT=off: Libexttextcat FTS support
====> GSSAPI Security API support: you have to select exactly one of them
GSSAPI_BASE=off: Use GSSAPI from base
GSSAPI_HEIMDAL=off: Use Heimdal GSSAPI from security/heimdal
GSSAPI_MIT=off: Use MIT GSSAPI from security/krb5
GSSAPI_NONE=on: Build without GSSAPI support
===> Use 'make config' to modify these settings
You must create the configuration files yourself. Copy them over
to /usr/local/etc/dovecot and edit them as desired:
cp -R /usr/local/etc/dovecot/example-config/* \
/usr/local/etc/dovecot
The default configuration includes IMAP and POP3 services, will
authenticate users agains the system's passwd file, and will use
the default /var/mail/$USER mbox files.
Next, enable dovecot in /etc/rc.conf:
dovecot_enable="YES"
To avoid a risk of mailbox corruption, do not set the
security.bsd.see_other_uids or .see_other_gids sysctls to 0
if Dovecot is storing mail for multiple concurrent users (PR 218392).
Similarly, setting sysctls security.bsd.hardlink_check_uid or
security.bsd.hardlink_check_gid to 1 might result in non-working
mailboxes, depending on what mailbox locking mechanism is used
(PR 242223).
If you want to be able to search within attachments using the
decode2text plugin, you'll need to install textproc/catdoc, and
one of graphics/xpdf or graphics/poppler-utils.
There are some potentially breaking changes in Dovecot 2.3. If you
are upgrading from Dovecot 2.2:
* https://doc.dovecot.org/2.3/installation_guide/upgrading/from-2.2-to-2.3/
* Merge the configuration file changes from
/usr/local/etc/dovecot/examples-config/
If removing:
If you are removing dovecot permanently, you should 'rm -rf /var/db/dovecot' to
clear out any remaining data.

mail/dovecot: update 2.3.21 → 2.3.21.1 (fixes 2 CVEs)
- CVE-2024-23184: A large number of address headers in email resulted
in excessive CPU usage.
- CVE-2024-23185: Abnormally large email headers are now truncated or
discarded, with a limit of 10MB on a single header and 50MB for all
the headers of all the parts of an email.
- oauth2: Dovecot would send client_id and client_secret as POST parameters
to introspection server. These need to be optionally in Basic auth
instead as required by OIDC specification.
- oauth2: JWT key type check was too strict.
- oauth2: JWT token audience was not validated against client_id as
required by OIDC specification.
- oauth2: XOAUTH2 and OAUTHBEARER mechanisms were not giving out
protocol specific error message on all errors. This broke OIDC discovery.
- oauth2: JWT aud validation was not performed if aud was missing
from token, but was configured on Dovecot.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

mail/dovecot, mail/dovecot-pigeonhole: Upgrade to 2.3.19, 0.5.19
Dovecot Changelog:
+ Added mail_user_session_finished event, which is emitted when the mail
user session is finished (e.g. imap, pop3, lmtp). It also includes
fields with some process statistics information.
See https://doc.dovecot.org/admin_manual/list_of_events/ for more
information.
+ Added process_shutdown_filter setting. When an event matches the filter,
the process will be shutdown after the current connection(s) have
finished. This is intended to reduce memory usage of long-running imap
processes that keep a lot of memory allocated instead of freeing it to
the OS.
+ auth: Add cache hit indicator to auth passdb/userdb finished events.

Dovecot ChangeLog:
* Removed mail_cache_lookup_finished event. This event wasn't especially
useful, but it increased CPU usage significantly.
* fts: Don't index inline base64 encoded content in FTS indexes using
the generic tokenizer. This reduces the FTS index sizes by removing
input that is very unlikely to be searched for. See
https://doc.dovecot.org/configuration_manual/fts/tokenization for
details on how base64 is detected. Only applies when using libfts.
* lmtp: Session IDs are now preserved through proxied connections, so
LMTP sessions can be tracked. This slightly changes the LMTP session
ID format by appending ":Tn" (transaction), ":Pn" (proxy connection)
and ":Rn" (recipient) counters after the session ID prefix.

mail/dovecot: Upgrade to 2.3.10.1, fixing multiple vulnerabilities.
- CVE-2020-10957: lmtp/submission: A client can crash the server by
sending a NOOP command with an invalid string parameter. This occurs
particularly for a parameter that doesn't start with a double quote.
This applies to all SMTP services, including submission-login, which
makes it possible to crash the submission service without
authentication.
- CVE-2020-10958: lmtp/submission: Sending many invalid or unknown
commands can cause the server to access freed memory, which can lead
to a server crash. This happens when the server closes the connection
with a "421 Too many invalid commands" error. The bad command limit
depends on the service (lmtp or submission) and varies between 10 to
20 bad commands.
- CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an
address that has the empty quoted string as local-part causes the
lmtp service to crash.
Clean up some REINPLACE warnings whilst we're here.

mail/dovecot: update to 2.3.10.
ChangeLog:
* Disable retpoline migitations by default. These can cause severe
performance regressions, so they should be only enabled when
applicable.
* IMAP MOVE now commits transactions in batches of 1000 mails. This
helps especially with lazy_expunge when moving a lot of mails. It
mainly avoids situations where multiple IMAP sessions are running the
same MOVE command and duplicating the mails in the lazy_expunge folder.
With this change there can still be some duplication, but the MOVE
always progresses forward. Also if the MOVE fails at some point, the
changes up to the last 1000 mails are still committed instead of
rolled back. Note that the COPY command behavior hasn't changed,
because it is required by IMAP standard to be an atomic operation.

* Events inheriting from a mailbox: Renamed "name" to "mailbox"
* Server connection events have only "remote_ip", "remote_port",
"local_ip" and "local_port".
* Removed duplicate "client_ip", "ip" and "port".
* Mail storage events: Removed "service" field.
