|
||
==============================================================================
|
||
|
||
postfix-policyd-spf-perl is a Postfix SMTPd policy daemon for SPF checking.
|
||
It is implemented in pure Perl and uses the Mail::SPF::Query CPAN module.
|
||
|
||
See INSTALL or README.Debian for installation instructions.
|
||
|
||
Usage:
|
||
policyd-spf-perl [-v]
|
||
|
||
This documentation assumes you have read Postfix's README_FILES/
|
||
SMTPD_POLICY_README.
|
||
|
||
Logging is sent to syslogd.
|
||
|
||
Each time a Postfix SMTP server process is started it connects to the policy
|
||
service socket, and Postfix runs one instance of this Perl script. By
|
||
default, a Postfix SMTP server process terminates after 100 seconds of idle
|
||
time, or after serving 100 clients. Thus, the cost of starting this Perl
|
||
script is smoothed out over time.
|
||
|
||
The default policy_time_limit is 1000 seconds. This may be to short for some
|
||
SMTP transactions to complete. As recommended in SMTPD_POLICY_README, this
|
||
should be extended to 3600 seconds. To do so, set "policy_time_limit = 3600"
|
||
in /etc/postfix/main.cf.
|
||
|
||
Testing the policy daemon
|
||
-------------------------
|
||
|
||
To test the policy daemon by hand, execute:
|
||
|
||
% perl /usr/lib/postfix/policyd-spf-perl
|
||
|
||
Each query is a bunch of attributes. Order does not matter, and the daemon
|
||
uses only a few of all the attributes shown below:
|
||
|
||
request=smtpd_access_policy
|
||
protocol_state=RCPT
|
||
protocol_name=SMTP
|
||
helo_name=some.domain.tld
|
||
queue_id=8045F2AB23
|
||
sender=foo@bar.tld
|
||
recipient=bar@foo.tld
|
||
client_address=1.2.3.4
|
||
client_name=another.domain.tld
|
||
[empty line]
|
||
|
||
The policy daemon will answer in the same style, with an attribute list
|
||
followed by a empty line:
|
||
|
||
action=dunno
|
||
[empty line]
