spamassassin updates
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

What special treatment is offered to connection with relay permission? Relay
|

|
permissions are granted when the connecting IP is listed in the relayclients

file and/or when the user has authenticated. The only valid option at present
|
||||||
|
is 'skip', which skips SA scoring.
|
||||||
|
|
||||||
|
If SpamAssasin has certain network tests enabled, users may get elevated spam
|
||||||
|
scores because their dynamic IP space is properly listed on DUL blocking lists.
|
||||||
|
If the user is authenticated or coming from a trusted IP, odds are we don't
|
||||||
|
want to be reject their messages. Especially when running qpsmtpd on port 587.

=head1 MULTIPLE RECIPIENT BEHAVIOR
|
||||||
|
|
||||||
|
This plugin supports per-user SpamAssassin preferences. When per-user SA prefs
|
||||||
|
are enabled (by setting spamd_user = vpopmail), the message recipient is used
|
||||||
|
as the spamd username. If SpamAssassin has per-user preferences enabled, it
|
||||||
|
will consult the users spam preferences when scoring the message.
|
||||||
|
|
||||||
|
When a message has multiple recipients, we do not change the spamd username.
|
||||||
|
The message is still scored by SA, but per-user preferences are not
|
||||||
|
consulted. To aid in debugging, messages with multiple recipents will
|
||||||
|
have an X-Spam-User header inserted. Admins and savvy users can look for
|
||||||
|
that header to confirm the reason their personal prefs were not consulted.
|
||||||
|
|
||||||
|
To get per-user SA prefs to work for messages with multiple recipients, the
|
||||||
|
LDA should be configured to check for the presence of the X-Spam-User header.
|
||||||
|
If the X-Spam-User header is present, the LDA should submit the message to
|
||||||
|
spamd for re-processing with the recipients address.

2012.04.02 - Matt Simerson
|
||||||
|
|
||||||
|
* refactored for ease of maintenance
|
||||||
|
* added support for per-user SpamAssassin preferences
|
||||||
|
* updated get_spam_results so that score=N.N works (as well as hits=N.N)
|
||||||
|
* rewrote the X-Spam-* header additions so that SA generated headers are
|
||||||
|
not discarded. Admin can alter SA headers with add_header in their SA
|
||||||
|
config. Subverting their changes there is unexpected. Making them read
|
||||||
|
code to figure out why is an unnecessary hurdle.
|
||||||
|
* added assemble_message, so we can calc content size which spamd wants
|
||||||
