#
# Exim ACL for greylisting. David Woodhouse <dwmw2@infradead.org>
#
# For full background on the logic behind greylisting and how this
# ACL works, see https://github.com/Exim/exim/wiki/SimpleGreylisting
#
GREYDB=/var/spool/exim/db/greylist.db
# UPDATING TO EXIM 4.94+
# ======================
#
# Previous versions of this ACL specified the sqlite database filename
# in the sqlite lookup strings directly, but since Exim 4.94 is it no
# longer permitted to mix "tainted" text which comes from the message
# itself, with the filename. Thus, you now have to set
#
# sqlite_dbfile = /var/spool/exim/db/greylist.db
#
# ... in the main configuration because it can't be specified within
# the ACL in this file any more.
# ACL for greylisting. Place reason(s) for greylisting into a variable named
# $acl_m_greylistreasons before invoking with 'require acl = greylist_mail'.
# The reasons should be separate lines of text, and will be reported in
# the SMTP rejection message as well as the log message.
# USING THIS ACL
# ==============
#
# First set sqlite_dbfile in the main configuration file to point to
# the greylist sqlite database, as described above.
#
# In your main ACLs, gather reason(s) for greylisting into a variable
# named $acl_m_greylistreasons before invoking this ACL with
# 'require acl = greylist_mail'. The reasons should be separate lines
# of text, and will be reported in the SMTP rejection message as well
# as the log message. Anything "suspicious" about the email can be
# used as criteria here — being HTML, having even a few SpamAssassin
# points, even lacking SPF authorisation (which is OK for greylisting
# although you should never reject outright for an SPF "failure"
# because of the flaws in SPF).
#
# Obviously you need to .include this file too in order to be able
# to invoke this greylist_mail ACL.
# HOW IT WORKS
# ============
#
# When a suspicious mail is seen, we temporarily reject it and wait to see
# if the sender tries again. Most spam robots won't bother. Real mail hosts
