# ==============================
# The following line is only used if you use a system-wide /etc/procmailrc.
# See procmailrc(5) for infos on what it exactly does, the short version:
# * It ensures that the correct user is passed to spamd if spamc is used
# * The folders the mail is filed to later on is owned by the user, not
# root.
DROPPRIVS=yes
# Pipe the mail through spamassassin (replace 'spamassassin' with 'spamc'
# if you use the spamc/spamd combination)
#
# The condition line ensures that only messages smaller than 500 kB
# (500 * 1024 = 512000 bytes) are processed by SpamAssassin. Most spam
# isn't bigger than a few k and working with big messages can bring
# SpamAssassin to its knees.
#
# The lock file ensures that only 1 spamassassin invocation happens
# at 1 time, to keep the load down.

# Mails with a score of 15 or higher are almost certainly spam (with 0.05%
# false positives according to rules/STATISTICS.txt). Let's put them in a
# different mbox. (This one is optional.)

* ^X-Spam-Level: \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

# All mail tagged as spam (eg. with a score higher than the set threshold)
# is moved to "probably-spam".

* ^X-Spam-Status: Yes
probably-spam
# Work around procmail bug: any output on stderr will cause the "F" in "From"
# to be dropped. This will re-add it.
# NOTE: This is probably NOT needed in recent versions of procmail
