Log message:
dovecot2: updated to 2.3.5.2

v2.3.5.2
* CVE-2019-10691: Trying to login with 8bit username containing
  invalid UTF8 input causes auth process to crash if auth policy is
  enabled. This could be used rather easily to cause a DoS. Similar
  crash also happens during mail delivery when using invalid UTF8 in
  From or Subject header when OX push notification driver is used.

Log message:
Security fix:

    * CVE-2019-7524: Missing input buffer size validation leads into
      arbitrary buffer overflow when reading fts or pop3 uidl header
      from Dovecot index. Exploiting this requires direct write access to
      the index files.

Log message:
Bump version after pkg update.

Log message:

From the upstream release-note:

NEWS:

+ Lua push notification driver: mail keywords and flags are provided
in MessageNew and MessageAppend events.

+ auth: When auth_policy_log_only=yes, only log what the policy server
response would do without actually doing it.
+ auth: Always log policy server decisions with auth_verbose=yes
- v2.3.[34]: doveadm log errors: Output was missing user/session
- lda: Debug log lines could have shown slightly corrupted
- login proxy: Login processes may have crashed in various ways when
login_proxy_max_disconnect_delay was set.
- imap: Fix crash with Maildir+zlib if client disconnects during APPEND
- lmtp proxy: Fix potential assert-crash
- lmtp/submission: Fix crash when SMTP client transaction times out
- submission: Split large XCLIENT commands to 512 bytes per command,
so Postfix accepts them.
- submission: Fix crash when client sends invalid BURL command
- submission: relay backend: VRFY command: Avoid forwarding 500 and
502 replies back to client.
- lib-http: Fix potential assert-crash when DNS lookup fails

Log message:
mail/dovecot2: update to 2.3.4.1

v2.3.4.1 2019-02-05  Aki Tuomi <aki.tuomi@open-xchange.com>

	* CVE-2019-3814: If imap/pop3/managesieve/submission client has
	  trusted certificate with missing username field
	  (ssl_cert_username_field), under some configurations Dovecot
	  mistakenly trusts the username provided via authentication instead
	  of failing.
	* ssl_cert_username_field setting was ignored with external SMTP AUTH,
	  because none of the MTAs (Postfix, Exim) currently send the
	  cert_username field. This may have allowed users with trusted
	  certificate to specify any username in the authentication. This bug
	  didn't affect Dovecot's Submission service.

Log message:
Provide declarations for kill() and SIGKILL to fix NetBSD-8 build.

Log message:
Move PKGPATH check after bsd.prefs.mk to fix circular dependency.

Log message:
dovecot2: updated to 2.3.4

2.3.4:
 * The default postmaster_address is now "postmaster@<user domain or
   server hostname>". If username contains the @domain part, that's
   used. If not, then the server's hostname is used.
 * "doveadm stats dump" now returns two decimals for the \ 
"avg" field.

 + Added push notification driver that uses a Lua script
 + Added new SQL, DNS and connection events.
   See https://wiki2.dovecot.org/Events
 + Added "doveadm mailbox cache purge" command.
 + Added events API support for Lua scripts
 + doveadm force-resync -f parameter performs "index fsck" while opening
   the index. This may be useful to fix some types of broken index files.
   This may become the default behavior in a later version.
