# The following section of the ACL is concerned with local parts that contain
# certain non-alphanumeric characters. Dots in unusual places are
# handled by this ACL as well.
#
# Non-alphanumeric characters other than dots are rarely found in genuine
# local parts, but are often tried by people looking to circumvent
# relaying restrictions. Therefore, although they are valid in local
# parts, these rules disallow certain non-alphanumeric characters, as
# a precaution.
#
# Empty components (two dots in a row) are not valid in RFC 2822, but Exim
# allows them because they have been encountered. (Consider local parts
# constructed as "firstinitial.secondinitial.familyname" when applied to
# a name without a second initial.) However, a local part starting
# with a dot or containing /../ can cause trouble if it is used as part of a
# file name (e.g. for a mailing list). This is also true for local parts that
# contain slashes. A pipe symbol can also be troublesome if the local part is
# incorporated unthinkingly into a shell command line.
#
# These ACL components will block recipient addresses that are valid
# from an RFC2822 point of view. We chose to have them blocked by
# default for security reasons.
#
# If you feel that your site should have less strict recipient
# checking, please feel free to change the default values of the macros
# defined in main/01_exim4-config_listmacrosdefs or override them from a
# local configuration file.
#
# Two different rules are used. The first one has a quite strict
# default, and is applied to messages that are addressed to one of the
# local domains handled by this host.
# The default value of CHECK_RCPT_LOCAL_LOCALPARTS is defined in
# main/01_exim4-config_listmacrosdefs:
# CHECK_RCPT_LOCAL_LOCALPARTS = ^[.] : ^.*[@%!/|`#&?]
# This blocks local parts that begin with a dot or contain a quite
# broad range of non-alphanumeric characters.

# CHECK_RCPT_REMOTE_LOCALPARTS = ^[./|] : ^.*[@%!`#&?] : ^.*/\\.\\./
# It allows local users to send outgoing messages to sites
# that use slashes and vertical bars in their local parts. It blocks
# local parts that begin with a dot, slash, or vertical bar, but allows
# these characters within the local part. However, the sequence /../ is
# barred. The use of some other non-alphanumeric characters is blocked.
# Single quotes might probably be dangerous as well, but they're
# allowed by the default regexps to avoid rejecting mails to Ireland.
# The motivation here is to prevent local users (or local users' malware)

This is an automatically generated message. An error has\n\
been found in your .forward file. Details of the error are\n\
reported below. While this error persists, you will receive\n\
a copy of this message for every message that is addressed\n\
to you. If your .forward file is a filter file, or if it is\n\
a non-filter file containing no valid forwarding addresses,\n\
a copy of each incoming message will be put in your normal\n\
mailbox. If a non-filter file contains at least one valid\n\
forwarding address, forwarding to the valid addresses will\n\
happen, and those will be the only deliveries that occur.
