helo - validate a HELO message delivered from a connecting host.
Includes the following tests:
is_in_badhelo
invalid_localhost
is_plain_ip
is_address_literal [N.N.N.N]
is_forged_literal
is_not_fqdn
no_forward_dns
no_reverse_dns
no_matching_dns
in apr_*_handler subs, return DECLINED when connection is not available to read (like during tests)
added 23 tests
deprecate action argument
'action log' did nothing, better logging controls available with loglevel
'action deny' -> reject 1
'action denysoft' => reject 1 reject_type temp
POD
use head2 for config options (instead of over, item, back)
added loglevel section
updated for replacement of action with reject options
consolidated POD at top of file
added example options to reject_type POD head
added an example loglevel entry
consolidated DENY[SOFT|DISCONNECT] logic into get_reject_type
added tests for get_reject_type
added POD description of spfquery note
changed spf_deny -> reject (and offered 4 more options, see POD for reject)
backwards compatible with old config settings
replicates qmail-smtpd SPF patch behavior
improved logging (again)
uses a stringy eval 'use Mail::SPF' in the register sub. If missing, warn and log the error, and don't register any hooks. This is much nicer error than the current, "*** Remote host closed connection unexpectedly." broken mail server that results from enabling the SPF plugin without Mail::SPF installed.
background: I noticed I was deferring valid emails with the SPF plugin at 'spf_deny 1', and without changing the code, there wasn't a way to change how ~all records were handled. This provides that flexibility.
minor changes to facilitate testing
improved error reporting of several failures
added p0f v2 compatibility to p0f v3 results: in addition to all the newer values, also report the old ones too.
These 3 auth plugins all have a data store they fetch the reference
password or hash from. They then match the attemped password or hash
against the reference. This consolidates the latter portion (validating
the password/hash) into Auth.pm.
* less duplicated code in the plugins.
* Pass validation consistently handled for these 3 plugins.
* less work to create new auth plugins
Also caches the CRAM-MD5 ticket. It could also cache user/pass info if
this was desirable.
fixed the vestiges of old plugin name 'denysoft_greylisting'
added ability to bypass greylisting based on geoip
deprecated 'mode [denysoft | testonly | off]
off wasn't useful
testonly & denysoft replaced by reject [ 0 | 1 ]
renamed DB from denysoft_greylist to greylist.dbm. Will use existing/legacy DB if present.
added DB pruning feature. Automatically prune the DB when qpsmtpd registers the plugin. Perhaps this should be a config option to enable?
added DB upgrade feature. Convert dotted quad IP addresses in DB to integers. Makes greylisting IPv6 compatible, since DB records are colon delimited.
exempt TLS connections from greylisting. The vast majority (perhaps all) of the SMTP clients that request encryption to my server are legit. We could add a config option for this, but this plugin already has a multitude of config options.
refactored much of the greylisting method into discreet subs
added 30 tests
added additional DEBUG level logging for p0f matches
POD changes:
replaced over, item N, back, with head2 (better formatted output)
better describe the current behavior of the plugin (some past behaviors no longer exist)
added TRIPLET section with example
added loglevel section
expanded POD
cleaned up stray EOL spaces
added lots of logging, with standardized [ pass | fail | skip ] prefixes
added reject_type option
use split for parsing dspam headers
use SA note instead of parsing headers
added reject = agree option
store & fetch dspam results in a note
refactored into small subs with unit tests.
parse SA header with split instead of regexp (more reliable)
store SA results in a 'spamassassin' transaction note
add strict and warnings pragma
renamed reject_threshold -> reject (backwards compatible)
added relayclient skip option and POD. Skips SA processing when relayclient is set
added MULTIPLE RECIPIENT BEHAVIOR topic to POD
unit tests for new methods are in t/auth.t
added PLAIN and LOGIN tests in auth_flat_file
Most tests are disabled unless an interactive terminal is detected and $ENV{QPSMTPD_DEVELOPER} is set.
on files in plugins dir:
fixed a number of POD errors
formatted some # comments into POD
removed bare 1; (these are plugins, not perl modules)
most instances of this were copy/pasted from a previous plugin that had it
removed instances of # vim ts=N ...
they weren't consistent, many didn't match .perltidyrc
on modules that failed perl -c tests, added 'use Qpsmtpd::Constants;'

Apparently the format of vpopmaild responses has been expanded and the responses
are conditional.
* Replaced the 'sometimes works' eq comparison with a regexp that always works.
* added tests for all 3 vpopmail plugins
* added cram-md5 auth support to auth_vpopmaild.
- these changes are in the previous TCPLOCAL patch. Documented here.
added p0f config option
added POD docs to explain usage
modified $dbdir selection logic. The previous logic failed when QPHOME was
not selected (as is the case when tests are being run).
Added '.' as the dir of last resort for $dbdir selection (others $EMPTY/dir
dumped greylisting database in / )
- These changes are included in this patch -
Added t/plugin_tests/greylisting, with greylist logic testing (tests are
disabled by default, as greylisting is disabled in config.sample/plugins)
Added example entry in config.sample/plugins

No longer have local value for trace_level() the first time through, which
was masking the global value (due to stupid search/replace error).
Don't call log() from trace_level() since it is only ever called from
within the varlog() sub when no logging plugin is registered.
* plugins/dnsbl
Config line option to use DENY_DISCONNECT instead of DENY (since any IP
on a blacklist should not have a chance to send anything for now).
Add POD to document the new disconnect behavior
* lib/Qpsmtpd.pm

* t/Test/Qpsmtpd.pm
Compatibility sub for core subs which call varlog() directly

o plugins/check_badmailfromto
- New plugin in the style of check_badmailfrom, which matches a pair
of FROM/TO and makes it seem like the recipient's address no longer
exists (but only from the matching sender's point of view). Useful
for stalkers and other harassment cases.
o plugins/dns_whitelist_soft
- New plugin to provide a DNS-based whitelist (good for distributed
sites).
o various files
- Replaced tab character with 8 spaces and adjusted line breaks for
better readability.
Changes by mct@toren.net (Michael C. Toren)
o lib/Qpsmtpd/SMTP.pm
- Assumes a MAIL FROM value of "<#@[]>" (utilized by qmail to
indicate a null sender when generating a doublebounce message)
is equivalent to "<>". Previously qpsmtpd complained that the
value could not be parsed.
- Adds LOGIN to the default list of supported auth mechanisms.
The documentation in Auth.pm indicated that auth-login was not
currently supported due to lack of functionality, however I can
confirm that LOGIN appears to work fine as tested by using msmtp
(http://msmtp.sourceforge.net/). Are there any indications that
LOGIN support is actually broken in the current implementation?
- Removes the "X-Qpsmtpd-Auth: True" header appended when a message
has been sent by an authenticated user. One problem with such a
header is that it's impossible to say which SMTP hop added it,
and it provides no information which could be used to backtrack
the transaction. I grepped through my mail archives a bit
looking for how other MTAs handled the problem, and decided it
would be best to place this information in the Received: header:
Received: from remotehost (HELO remotehost) (192.168.42.42)
(smtp-auth username foo, mechanism cram-md5)
by mail.netisland.net (qpsmtpd/0.28) with ESMTP; <date>
o lib/Qpsmtpd/Auth.pm:
- Documentation update for the arguments passed to an auth
handler; previously the $mechanism argument was not mentioned,
which threw off the argument offsets.
- Documentation update for auth-login removing the warning
that auth-login is not currently supported due to lack of
functionality.
- Fix to execute a generic auth hook when a more specific
auth-$mechanism hook does not exist. (Previously posted
to the list last week.)
- Upon authentication, sets $session->{_auth_user} and
$session->{_auth_mechanism} so that SMTP.pm can include them
in the Received: header.
o plugins/queue/qmail-queue
- Added a timestamp and the qmail-queue qp identifier to the
"Queued!" 250 message, for compatibility with qmail-smtpd, which
can be very useful for tracking message delivery from machine to
machine. For example, the new 250 message might be:
250 Queued! 1105927468 qp 3210 <1105927457@netisland.net>
qmail-smtpd returns:
250 ok 1106546213 qp 7129
Additionally, for consistency angle brackets are placed around
the Message-ID displayed in the 250 if they were missing in the
message header.
o plugins/check_badmailfrom:
- Changed the error message from "Mail from $bad not accepted
here" to "sorry, your envelope sender is in my badmailfrom
list", for compatibility with qmail-smtpd. I didn't see any
reason to share with the sender the value of $bad, especially
for situations where the sender was rejected resulting from a
wildcard.
o plugins/check_earlytalker:
o plugins/require_resolvable_fromhost:
- No longer checks for earlytalkers or resolvable senders if the
connection note "whitelistclient" is set, which is nice for
helping backup MX hosts empty their queue faster.
o plugins/count_unrecognized_commands:
- Return code changed from DENY_DISCONNECT, which isn't valid in
an unrecognized_command hook, to DENY, which in this context
drops the connection anyway. (Previously posted to the list
last week.)
