Tárgy: [Exim] bogged down server.. config problem?..
hi, my server is bogged down with connection attempts from spammers..
ive set up blacklist support.. in an ACL but that hasn't really solved the
problem.

exim ends up using all resources.. and the system can't process the mail.
please take a look at the below exim.conf file and see if you have any
suggestions.. to what the problem could be.

thanks alot!
steve

# of all the runtime configuration options that can be included in a

# manual is in the file doc/spec.txt in the Exim distribution as a plain
# ASCII file. Other formats (PostScript, Texinfo, HTML) are available from
# the Exim ftp sites. The manual is also online via the Exim web sites.


# This file is divided into several parts, all but the last of which are
# terminated by a line containing the word "end". The parts must appear
# in the correct order, and all must be present (even if some of them are
# in fact empty). Blank lines, and lines starting with # are ignored.

# address, but the string "caesar" (i.e. just a login name) is an
unqualified
# email address. Unqualified addresses are accepted only from local callers
by
# default. See the receiver_unqualified_{hosts,nets} options if you want
# to permit unqualified addresses from remote sources. If this option is

# qualify_recipient value is used as the only local domain. If you do not
want
# to do any local deliveries, uncomment the following line, but do not
supply
# any data for it. This sets local_domains to an empty string, which is not
# the same as not mentioning it at all. An empty string specifies that there
# are no local domains; not setting it at all causes the default value (the
# setting of qualify_recipient) to be used.

# No local deliveries will ever be run under the uids of these users (a

the
# uid of "nobody" instead. This is a paranoic safety catch. Note the default

#
# If you want to permit relaying through your host from certain hosts or IP
# networks, you need to set the option appropriately, for example
#
#
#
# If you are an MX backup or gateway of some kind for some domains, you must
# set relay_domains to match those domains. This will allow any host to
# relay through your host to those domains.
#
# See the section of the manual entitled "Control of relaying" for more
# information.

# 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.

# By default, Exim expects all envelope addresses to be fully qualified,
that
# is, they must contain both a local part and a domain. If you want to
accept
# unqualified addresses (just a local part) from certain hosts, you can
specify
# these hosts by setting one or both of
#
# receiver_unqualified_hosts =
# sender_unqualified_hosts =
#
# to control sender and receiver addresses, respectively. When this is done,
# unqualified addresses are qualified using the settings of qualify_domain
# and/or qualify_recipient (see above).


# Exim contains support for the Realtime Blocking List (RBL) that is being
# maintained as part of the DNS. See http://maps.vix.com/rbl/ for
background.
# Uncommenting the first line below will make Exim reject mail from any
# host whose IP address is blacklisted in the RBL at maps.vix.com. Some
# others have followed the RBL lead and have produced other lists: DUL is
# a list of dial-up addresses, and ORBS is a list of open relay systems. The
# second line below checks all three lists.

# If you want Exim to support the "percent hack" for all your local domains,
# uncomment the following line. This is the feature by which mail addressed
