rather than deferring until RCPT. This greatly improves efficiency, since most connections will get marked naughty much sooner, having run fewer tests.
consolidate the two data_post methods into one (more linear, simpler)
more informative log message
add new headers to top of headers (not bottom (consistent MTA behavior))
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.
