Postfix greylisting policy server

Postgrey is a Postfix policy server implementing greylisting. When a
request for delivery of a mail is received by Postfix via SMTP, the
triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first
time that this triplet is seen, or if the triplet was first seen less
than 5 minutes, then the mail gets rejected with a temporary error.
Hopefully spammers or viruses will not try again later, as it is
however required per RFC.

The following features compared with greylist.pl from Postfix 2.1.1 are
new: Safe database, automatic maintenance, whitelists, lookup by
subnet, auto-whitelisting of clients, only Berkeley DB and no large
mysql nor postgresql DB needed.

Dominique Leuenberger Dominique Leuenberger (dimstar_suse) accepted request 435745 6 days ago (revision 32)
- Update to 1.37:
  * added initial test suite
  * testing using travis-ci (https://travis-ci.org/schweikert/postgrey)
  * removed IP pool-detection code for --lookup-by-net, because it matched
    also the naming of some big hosters like facebook (#32, Michal Petrucha,
    Andrew Ayer, Jon Sailor)
  * fix early logging of errors and warnings to syslog
  * simplified IP matching code
  * added support for IPv6 whitelists with netmask
  * add network-range based whitelist for Office 365 (Holger Stember)
  * updated whitelist
- postgrey-1.36-config.patch renamed to postgrey-1.37-config.patch
  and rebased to new version.
