Description-en: external policy checker for the postfix mail server
Tumgreyspf can optionally greylist and/or use spfquery to check SPF records
to determine if email should be accepted by your server. The default behavior
is to let emails comming from server that are SPF approved without any sort
of greylisting, while all others will be greylisted.
.
SPF is information published by the domain owner about what systems may
legitimately send e-mail for the domain. Greylisting takes advantage of spam
and viruses that do not follow the RFCs and retry deliveries on temporary
failure. These checks can be used as part of a mail system and allow several
orders of magnitude reduction in spam, lower system load, and few problems
with legitimate mail getting blocked.
.
Tumgreyspf uses the file-system as its database, no additional database is
required to use it, see /var/lib/tumgreyspf/data and it's clean-up cron
script. Also take care that tumgreyspf will block emails from any domain with
DNS configured with a buggy SPF record.
