Previously the greylist plugin tried to use redis and fell back to DBM. This means that if a system already had an established DBM database, but happened to have Redis running, the existing DBM db would be abandoned for a new Redis DB. This would inevitably lead to more delays for legitimate mail, and possibly lost mail.
This adds a 'redis_server' argument which enables Redis and sets the location of the redis server; if it is not explicitly set, DBM is used instead.
If the redis server is unavailable, rather than failing to start QP, we instead fail to register the plugin.
These are noops: clients that retry before grey_timeout is exceeded and
clients that retry after grey_timeout is exceeded all pass greylisting until
expired by white_timeout.
This does not drop support for including the recipient in the greylist key.
Note that this was already broken for an indeterminate (long) amount of time
* includes full test converage for Qpsmtpd::Config
* folded t/config.t into t/qpsmtpd-config.t
* includes additional tests for Qpsmtpd
* folded t/tempstuff into t/qpsmtpd.t
* PBP adjustments here and there
* other tweaks to handle test warnings
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
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;'

(patch remade against latest rspier/qpsmtpd)
added remote_port, local_ip, local_port, and local_host to $qp->connection, as the p0f plugin relies on it.
added notes to TcpServer.pm and the p0f plugin noting the dependence, and the lack of support for models other than tcpserver.
