# Function:
# Access Control for this smtp server - determines:
# * Who we accept mail from
# * Who we accept relaying from
# * Who we will not send to
#
# Usage:
# FEATURE(access_db[, type [-o] /etc/mail/access])dnl
# makemap hash access < access
#
# Format:
# lhs:
# email addr <user@[host.domain]>
# domain name unless FEATURE(relay_hosts_only) is used,
# then this is a fqdn - and relay-domains ($=R)
# must also be fqdns.
# network number must end on an octet boundary, or
# you're stuck going the longwinded way ;-{
# rhs:
# OK accept mail even if other rules in the
# running ruleset would reject it.
# RELAY Allow domain to relay through your SMTP
# server. RELAY also serves an implicit
# OK for the other checks.
# REJECT reject the sender/recipient with a general
# purpose message that can be customized.
# confREJECT_MSG [550 Access denied] will be issued
# DISCARD discard the message completely using
# the $#discard mailer.
# ### any text where ### is an RFC 821 compliant error code
# and "any text" is a message to return for
# the command
# Examples:
# [email protected] REJECT
# FREE.STEALTH.MAILER@ 550 Spam not accepted
#
# Notes:
# With FEATURE(blacklist_recipients) this is also possible:
# badlocaluser 550 Mailbox disabled for this username
# host.mydomain.com 550 That host does not accept mail
# [email protected] 550 Mailbox disabled for this recipient
