mail: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

The following distfiles were unfetchable (possibly fetched
conditionally?):

./mail/qmail/distinfo netqmail-1.05-TAI-leapsecs.patch

Log message:
mail: Remove SHA1 hashes for distfiles

Log message:
comms/sendmail: update to 8.16.1

8.16.1/8.16.1	2020/07/05
	SECURITY: If sendmail tried to reuse an SMTP session which had
		already been closed by the server, then the connection
		cache could have invalid information about the session.
		One possible consequence was that STARTTLS was not
		used even if offered.  This problem has been fixed
		by clearing out all relevant status information
		when a closed session is encountered.
	OpenSSL versions before 0.9.8 are no longer supported.
	OpenSSL version 1.1.0 and 1.1.1 are supported.
	Initial support for DANE (see RFC 7672 et.al.) is available if
		the compile time option DANE is set.  Only TLSA RR 3-1-x
		is currently implemented.
	New options SSLEngine and SSLEnginePath to support OpenSSL engines.
		Note: this feature has so far only been tested with the
		"chil" engine; please report problems with other engines
		if you encounter any.
	New option CRLPath to specify a directory which contains
		hashes pointing to certificate revocations files.
		Based on patch from Al Smith.
	New rulesets tls_srv_features and tls_clt_features which
		can return a (semicolon separated) list of TLS related
		options, e.g., CipherList, CertFile, KeyFile,
		see doc/op/op.me for details.
	To automatically handle TLS interoperability problems for outgoing
		mail, sendmail can now immediately try a connection again
		without STARTTLS after a TLS handshake failure.
		This can be configured globally via the option
		TLSFallbacktoClear or per session via the 'C' flag
		of tls_clt_features.
		This also adds the new value "CLEAR" for the macro
		{verify}: STARTTLS has been disabled internally for
		a clear text delivery attempt.
	Apply Timeout.starttls also to the server waiting for the TLS
		handshake to begin.  Based on patch from Simon Hradecky.
	New compile time option TLS_EC to enable the use of elliptic
		curve cryptography in STARTTLS (previously available as
		_FFR_TLS_EC).
	Handle MIME boundaries specified in headers which contain CRLF.
	Fix detection of loopback net (it was broken when compiled
		with NETINET6) and only set the macros {if_addr_out}
		and {if_family_out} if the interface of the outgoing
		connection does not belong to the loopback net.
	Fix logic to enable a milter to delete a recipient in
		DeliveryMode=interactive even if it might be subject
		to alias expansion.
	Log name of a milter making changes (this was missing for
		some functions).
	Log the actual reply of a server when an SMTP delivery problem
		occurs in a "reply=" field if possible.
	Log user= for failed AUTH attempts if possible.  Based on
		patch from Packet Hack, Jim Hranicky, Kevin A. McGrail,
		and Joe Quinn.
	Add CDB as map type. Note: CDB is a "Constant DataBase", i.e.,
		no changes can be made after it is created, hence it
		does not work with vacation(1) nor editmap(8) (except
		for query mode).
	Fix some memory leaks (mostly in error cases) and properly handle
		copied varargs in sm_io_vfprintf(). The issues were found
		using Coverity Scan and reported (including patches) by
		Ondřej Lysoněk of Red Hat.
	Do not override ServerSSLOptions and ClientSSLOptions when they
		are specified on the command line.  Based on patch from
		Hiroki Sato.
	Add RFC7505 Null MX support for domains that declare they do not
		accept mail.
	New compile time option LDAP_NETWORK_TIMEOUT which is set
		automatically when LDAPMAP is used and
		LDAP_OPT_NETWORK_TIMEOUT is available to enable the
		new -c option for LDAP maps to specify the network timeout.
	CONFIG: New FEATURE(`tls_session_features') to enable standard
		rules for tls_srv_features and tls_clt_features; for
		details see cf/README.
	CONFIG: New options confSSL_ENGINE and confSSL_ENGINE_PATH
		for SSLEngine and SSLEnginePath, respectively.
	CONFIG: New options confDANE to enable DANE support.
	CONFIG: New option confTLS_FALLBACK_TO_CLEAR for TLSFallbacktoClear.
	CONFIG: New extension CITag: for TLS restrictions, see cf/README
		for details.
	CONFIG: FEATURE(`blacklist_recipients') renamed to
		FEATURE(`blocklist_recipients').
	CONTRIB: cidrexpand updated to support IPv6 CIDR ranges and to
		canonicalize IPv6 addresses; if cidrexpand is used with IPv6
		addresses then UseCompressedIPv6Addresses must be disabled.
	DOC: The dns map can return multiple values in a single result
		if the -z option is used.
	DOC: Note to set MustQuoteChars=. due to DKIM signatures.
	LIBMILTER: Fix typo in a macro. Patch from Ignacio Goyret
		of Alcatel-Lucent.
	LIBMILTER: Fix reference in xxfi_negotiate documentation.
		Patch from Sven Neuhaus.
	LIBMILTER: Fix function name in smfi_addrcpt_par documentation.
		Patch from G.W. Haywood.
	LIBMILTER: Fix a potential memory leak in smfi_setsymlist().
		Patch from Martin Svec.
	MAKEMAP: New map type "implicit" refers to the first available type,
		i.e., it depends on the compile time options NEWDB, DBM,
		and CDB. This can be used in conjunction with the
		"implicit" map type in sendmail.cf.
		Note: makemap, libsmdb, and sendmail must be compiled
		with the same options (and library versions of course).
	Portability:
		Add support for Darwin 14-18 (Mac OS X 10.x).
		New option HAS_GETHOSTBYNAME2: set if your system
		supports gethostbyname2(2).
		Set SM_CONF_SEM=2 for FreeBSD 12 and later due to
		changes in sys/sem.h
		On Linux set MAXHOSTNAMELEN (the maximum length
		of a FQHN) to 256 if it is less than that value.
	Added Files:
		cf/feature/blocklist_recipients.m4
		cf/feature/tls_failures.m4
		devtools/OS/Darwin.14.x
		devtools/OS/Darwin.15.x
		devtools/OS/Darwin.16.x

mail/sendmail: fix build in SUBST_NOOP_OK=no mode

Log message:
Bug fix, submitted upstream

Add missing curly brackets that caused res_ninit() to be called
with non-zeroed state structure. In NetBSD, res_ninit() detects
the mistake and quickly calls res_ndestroy(), which will close file
descriptors based on the random data provided in the state structure.
The result at mine is sendmail going mute after the MAIL FROM
command.

Log message:
Allow the UseBlacklist configuration option, but ignore it, on
systems that don't have blacklistd.  This prevents configuration
errors as the default config files have:

O UseBlacklist=false

Log message:
*: Recursive revision bump for openssl 1.1.1.

Log message:
To resole hostname to IPv6 addresses gethostbyname2() is needed.
Fix spurious (may be forged) logs when receiving via IPv6 socket,
and fix sending to IPv6-enabled relay.
Bump PKGREVISION
(no revision bump for libmilter, it's not affected)

Log message:
Fix build problems on systems that don't have blacklistd.  Since
this is a build fix, no PKGREVISION bump is needed.

Log message:
Woops, didn't properly comment out a line that was disabling the
use of res_n* functions.
