Приветствую всех,
Столкнулся с такой проблемой, что exim возвращает назад некоторые письма: - "This message has been rejected because it has a potentially executable attachment".
Насколько я узнал, за это отвечает acl_check_data
в моем конфиге, оно прописано как
# ACL that is used after the DATA command
check_message:
accept
и больше ничего(хотя это по идее значит: - "принимать всю почту")
вот полный конфиг

######### IMPORTANT ########## IMPORTANT ########## IMPORTANT ########
# #
# Whenever you change Exim's configuration file, you *must* remember #
# to HUP the Exim daemon, because it will not pick up the new #
# configuration until you do. However, any other Exim processes that #
# are started, for example, a process started by an MUA in order to #
# send a message, will see the new configuration as soon as it is in #
# place. #
# #
# You do not need to HUP the daemon for changes in auxiliary files #
# that are referenced from this file. They are read every time they #
# are used. #
# #
# It is usually a good idea to test a new configuration for #
# syntactic correctness before installing it (for example, by #
# running the command "exim -C /config/file.new -bV"). #

# above. You also need to comment "forbid_domain_literals" below. This is not
# recommended for today's Internet.
# DO NOT ALLOW HOST LITERALS
# OPTIONAL MODIFICATIONS:
# These defaults work for us; you may wish to uncomment the line
# below and change the allow_domain_literals line below to true
# to allow domain literals in your environment
# local_domains_include_host_literals
# The following line prevents Exim from recognizing addresses of the form
# "user@[111.111.111.111]" that is, with a "domain literal" (an IP address)
# instead of a named domain. The RFCs still require this form, but it makes
# little sense to permit mail to be sent to specific hosts by their IP address
# in the modern Internet, and this ancient format has been used by those
# seeking to abuse hosts by using them for unwanted relaying. If you really
# do want to support domain literals, remove the following line, and see
# also the "domain_literal" router below.
allow_domain_literals = false
# No local deliveries will ever be run under the uids of these users (a colon-
# separated list). An attempt to do so gets changed so that it runs under the
# uid of "nobody" instead. This is a paranoic safety catch. Note the default
# setting means you cannot deliver mail addressed to root as if it were a
# normal user. This isn't usually a problem, as most sites have an alias for
# root that redirects such mail to a human administrator.
never_users = root
# DO HOST LOOKUP
# OPTIONAL MODIFICATIONS:
# The setting below causes Exim to do a reverse DNS lookup on all incoming
# IP calls, in order to get the true host name. If you feel this is too
# expensive, you can specify the networks for which a lookup is done, or
# remove the setting entirely.
host_lookup = *
# DISALLOW IDENT CALLBACKS
# OPTIONAL MODIFICATIONS:
# Exim may be set to make RFC 1413 (ident) callbacks for all incoming SMTP
# calls. You can limit the hosts to which these calls are made, and/or change
# the timeout that is used. If you set the timeout to zero, all RFC 1413 calls
# are disabled. RFC 1413 calls are cheap and can provide useful information
# for tracing problem messages, but some hosts and firewalls have problems
# with them. This can result in a timeout instead of an immediate refused
# connection, leading to delays on starting up an SMTP session. By default
# we disable callbacks for incoming SMTP calls. You may change
# rfc1413_query_timeout to 30s or some other positive number of seconds to
# enable callbacks for incoming SMTP calls.
rfc1413_hosts = *
rfc1413_query_timeout = 0s
# BOUNCE MESSAGES
# OPTIONAL MODIFICATIONS:
# When Exim can neither deliver a message nor return it to sender, it
# "freezes" the delivery error message (aka "bounce message"). There are also
# other circumstances in which messages get frozen. They will stay on the
# queue forever unless one or both of the following options is set.
# This option unfreezes bounce messages after two days, tries
# once more to deliver them, and ignores any delivery failures.
ignore_bounce_errors_after = 2d
# This option cancels (removes) frozen messages that are older than five days.
timeout_frozen_after = 5d

# Initial release
# 0.02 8 May 2000
# Widened list of content-types accepted, added WSF extension
# 0.03 8 May 2000
# Embedded the install notes in for those that don't do manuals
# 0.04 9 May 2000
# Check global content-type header. Efficiency mods to REs
# 0.05 9 May 2000
# More minor efficiency mods, doc changes
# 0.06 20 June 2000
# Added extension handling - thx to Douglas Gray Stephens & Jeff Carnahan
# 0.07 19 July 2000
# Latest MS Outhouse bug catching
# 0.08 19 July 2000
# Changed trigger length to 80 chars, fixed some spelling
# 0.09 29 September 2000
# More extensions... its getting so we should just allow 2 or 3 through
# 0.10 18 January 2001
# Removed exclusion for error messages - this is a little nasty
# since it has other side effects, hence we do still exclude
# on unix like error messages
# 0.11 20 March, 2001
# Added CMD extension, tidied docs slightly, added RCS tag
# ** Missed changing version number at top of file :-(
# 0.12 10 May, 2001
# Added HTA extension
# 0.13 22 May, 2001
# Reformatted regexps and code to build them so that they are
# shorter than the limits on pre exim 3.20 filters. This will
# make them significantly less efficient, but I am getting so
# many queries about this that requiring 3.2x appears unsupportable.
# 0.14 15 August,2001
# Added .lnk extension - most requested item :-)
# Reformatted everything so its now built from a set of short
# library files, cutting down on manual duplication.
# Changed \w in filename detection to . - dodges locale problems
# Explicit application of GPL after queries on license status
# 0.15 17 August, 2001
# Changed the . in filename detect to \S (stops it going mad)
# 0.16 19 September, 2001
# Pile of new extensions including the eml in current use
# 0.17 19 September, 2001
# Syntax fix
#
#### Install Notes
#
# Exim filters run the exim filter language - a very primitive
# scripting language - in place of a user .forward file, or on
# a per system basis (on all messages passing through).
# The filtering capability is documented in the main set of manuals
# a copy of which can be found on the exim web site
#
http://www.exim.org/ #
# To install, copy the filter file (with appropriate permissions)
# to /etc/exim/system_filter.exim and add to your exim config file
# [location is installation depedant - typicaly /etc/exim/config ]
# in the first section the line:-
# message_filter = /etc/exim/system_filter.exim
# message_body_visible = 5000
#
# You may also want to set the message_filter_user & message_filter_group
# options, but they default to the standard exim user and so can
# be left untouched. The other message_filter_* options are only
# needed if you modify this to do other functions such as deliveries.
# The main exim documentation is quite thorough and so I see no need
# to expand it here...
#
# Any message that matches the filter will then be bounced.
# If you wish you can change the error message by editing it
# in the section above - however be careful you don't break it.
#
# After install exim should be restarted - a kill -HUP to the
# daemon will do this.
#
#### LIMITATIONS
#
# This filter tries to parse MIME with a regexp... that doesn't
# work too well. It will also only see the amount of the body
# specified in message_body_visible
#
#### BASIS
#
# The regexp that is used to pickup MIME/uuencoded body parts with
# quoted filenames is replicated below (in perl format).
# You need to remember that exim converts newlines to spaces in
# the message_body variable.
#
# (?:Content- # start of content header
# (?:Type: (?>\s*) # rest of c/t header
# [\w-]+/[\w-]+ # content-type (any)
# |Disposition: (?>\s*) # content-disposition hdr
# attachment) # content-disposition
# ;(?>\s*) # ; space or newline
# (?:file)?name= # filename=/name=
# |begin (?>\s+) [0-7]{3,4} (?>\s+)) # begin octal-mode
# (\"[^\"]+\. # quoted filename.
# (?:ad[ep] # list of extns

рестартовал екзима, а реакции никакой… тогда более того, закоментил вообще строку system_filter = /etc/system_filter.exim в exim.conf… рестартавал, а он как откидывал эти письма… так и откидывает.
Помогите пожалуйста – пользователи убивают :”-(…
