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
