System Requirements
|
|
-------------------
|
|
|
|
The following Perl version and packages are required for running
|
|
postfix-policyd-spf-perl:
|
|
|
|
Perl 5.6
|
|
version
|
|
NetAddr-IP 4
|
|
Mail::SPF (not Mail-SPF-Query) version 2.006 or later
|
|
Sys::Hostname::Long
|
|
Sys::Syslog
|
|
|
|
Installing
|
|
----------
|
|
|
|
1. Copy postfix-policyd-spf-perl to /usr/local/lib/policyd-spf-perl
|
|
|
|
2. Add the following to /etc/postfix/master.cf:
|
|
|
|
policy unix - n n - 0 spawn
|
|
user=nobody argv=/usr/local/lib/policyd-spf-perl
|
|
|
|
3. Configure the Postfix policy service in /etc/postfix/main.cf:
|
|
|
|
smtpd_recipient_restrictions =
|
|
...
|
|
reject_unauth_destination
|
|
check_policy_service unix:private/policy
|
|
...
|
|
|
|
NOTES:
|
|
Specify check_policy_service AFTER reject_unauth_destination or
|
|
else your system can become an open relay.
|
|
|
|
The user 'nobody' is used in this example. This is appropriate if you
|
|
do not have any other services running as nobody. If you do, create a
|
|
dedicated user for this service and use it instead.
|
|
|
|
4. Add "policy_time_limit = 3600" to main.cf
|
|
|
|
5. Restart Postfix.
