Szerző: Patrick O'Neal Dátum: CC: exim-users Tárgy: Re: [Exim] Exim 4.3 on Gentoo Linux
You sure you are ready for this.... This is so long... Okay, I actually
do have Exim running, and all of the other programs running that I
mentioned, but I am trying to use exim to relay mail to a smart host, as
I am on a dsl connection in a dialup pool. My problem is that I am
having all kinds of client authentication problems.. Now, upon the
advice of a brother of mine, instead of using PAM directly for
authentication, I compiled in cyrus-sasl (which is using PAM to
authenticate with.. Maybe I should change that to shadow? this suddenly
occurs to me.) support into exim and gentoo. After I actually got
Cyrus-Sasl to actually start, and run, I am still having authentication
issues like the following:
2004-02-04 01:57:35 fixed_login authenticator failed for
computername.here [192.168.1.37]: 535 Incorrect authentication data
(set_id=usernamehere)
I get the same things whether I use plain, or login for authentication.
I am including a copy of my config file, and hopefully no one will laugh
as it is very dirty right now as I have been commenting things on and
off to see if I can get everything to work right.

# manual is in the file doc/spec.txt in the Exim distribution as a plain
# ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are
available
# from the Exim ftp sites. The manual is also online at the Exim web
sites.
# This file is divided into several parts, all but the first of which

# 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
#

# MAIN CONFIGURATION SETTINGS #
######################################################################
# Specify your host's canonical name here. This should normally be the
fully
# qualified "official" name of your host. If this option is not set, the
# uname() function is called to obtain the name. In many cases this does
# the right thing and you need not set anything explicitly.
primary_hostname = jeremiah.xxxxxx.info
# The next three settings create two lists of domains and one list of
hosts.
# These lists are referred to later in this configuration using the
syntax
# +local_domains, +relay_to_domains, and +relay_from_hosts,
respectively. They
# are all colon-separated lists:
# YOU HAVE TO EDIT THIS BLOCK TO SUIT YOUR NEED!!
domainlist local_domains = xxxxxxxx.info
domainlist relay_to_domains =
#domainlist dead_and_dying = example.com:jexample.com
hostlist relay_from_hosts = 127.0.0.1 : 192.168.1.0/24
AUTH_PLAINTEXT=yes
# Most straightforward access control requirements can be obtained by
# appropriate settings of the above options. In more complicated
situations, you
# may need to modify the Access Control List (ACL) which appears later
in this
# file.
# The first setting specifies your local domains, for example:
#
# domainlist local_domains = my.first.domain : my.second.domain
#
# You can use "@" to mean "the name of the local host", as in the
default
# setting above. This is the name that is specified by primary_hostname,
# as specified above (or defaulted). If you do not want to do any local
# deliveries, remove the "@" from the setting above. If you want to
accept mail
# addressed to your host's literal IP address, for example, mail
addressed to
# "user@???", you can add "@[]" as an item in the local
domains
# list. You also need to uncomment "allow_domain_literals" below. This
is not
# recommended for today's Internet.
# The second setting specifies domains for which your host is an
incoming relay.
# If you are not doing any relaying, you should leave the list empty.
However,
# if your host is an MX backup or gateway of some kind for some domains,
you
# must set relay_to_domains to match those domains. For example:
#
# domainlist relay_to_domains = *.myco.com : my.friend.org
#
# 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 third setting specifies hosts that can use your host as an
outgoing relay
# to any other host on the Internet. Such a setting commonly refers to a
# complete local network as well as the localhost. For example:
#
# hostlist relay_from_hosts = 127.0.0.1 : 192.168.0.0/16
#
# The "/16" is a bit mask (CIDR notation), not a number of hosts. Note
that you
# have to include 127.0.0.1 if you want to allow processes on your host
to send
# SMTP mail by using the loopback address. A number of MUAs use this
method of
# sending mail.
# All three of these lists may contain many different kinds of item,
including
# wildcarded names, regular expressions, and file lookups. See the
reference
# manual for details. The lists above are used in the access control
list for
# incoming messages. The name of this ACL is defined here:
acl_smtp_rcpt = acl_check_rcpt
# You should not change that setting until you understand how ACLs work.
# The following ACL entry is used if you want to do content scanning
with the
# exiscan-acl patch. When you uncomment this line, you must also review
the
# acl_check_content entry in the ACL section further below.
acl_smtp_data = acl_check_content
# This configuration variable defines the virus scanner that is used
with
# the 'malware' ACL condition of the exiscan acl-patch. If you do not
use
# virus scanning, leave it commented. Please read
doc/exiscan-acl-readme.txt
# for a list of supported scanners.
# The following setting is only needed if you use the 'spam' ACL
condition
# of the exiscan-acl patch. It specifies on which host and port the
SpamAssassin
# "spamd" daemon is listening. If you do not use this condition, or you
use
# the default of "127.0.0.1 783", you can omit this option.
spamd_address = 127.0.0.1 783
# Specify the domain you want to be added to all unqualified addresses
# here. An unqualified address is one that does not contain an "@"
character
# followed by a domain. For example, "caesar@???" is a fully
qualified
# 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 recipient_unqualified_hosts option if you want to
permit
# unqualified addresses from remote sources. If this option is not set,
the
# primary_hostname value is used for qualification.
qualify_domain = xxxxxx.info
# If you want unqualified recipient addresses to be qualified with a
different
# domain to unqualified sender addresses, specify the recipient domain
here.
# If this option is not set, the qualify_domain value is used.

# The following line must be uncommented if you want Exim to recognize
# addresses of the form "user@???" 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. 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, uncomment the following
line, and
# see also the "domain_literal" router below.

# No deliveries will ever be run under the uids of these users (a colon-
# separated list). An attempt to do so causes a panic error to be
logged, and
# the delivery to be deferred. This is a paranoic safety catch. Note
that 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
# The setting below causes Exim to do a reverse DNS lookup on all

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

specify
# these hosts by setting one or both of
#
# sender_unqualified_hosts =
# recipient_unqualified_hosts =
#
# to control sender and recipient addresses, respectively. When this is
done,
# unqualified addresses are qualified using the settings of
qualify_domain
# and/or qualify_recipient (see above).
# If you want Exim to support the "percent hack" for certain domains,
# uncomment the following line and provide a list of domains. The
"percent
# hack" is the feature by which mail addressed to x%y@z (where z is one
of
# the domains listed) is locally rerouted to x@y and sent on. If z is
not one
# of the "percent hack" domains, x%y is treated as an ordinary local
part. This
# hack is rarely needed nowadays; you should not enable it unless you
are sure
# that you really need it.
#
# percent_hack_domains =

# As well as setting this option you will also need to remove the test
# for local parts containing % in the ACL definition below.
# 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 for
# ever unless one of the following options is set.
# This option unfreezes frozen bounce messages after two days, tries
# once more to deliver them, and ignores any delivery failures.

######################################################################
# THE ORDER IN WHICH THE ROUTERS ARE DEFINED IS IMPORTANT! #
# An address is passed to each router in turn until it is accepted. #
######################################################################
begin routers
# This router routes to remote hosts over SMTP by explicit IP address,
# when an email address is given in "domain literal" form, for example,
# <user@???>. The RFCs require this facility. However, it is
# little-known these days, and has been exploited by evil people seeking
# to abuse SMTP relays. Consequently it is commented out in the default
# configuration. If you uncomment this router, you also need to
uncomment
# allow_domain_literals above, so that Exim can recognize the syntax of
# domain literal addresses.
# This router routes addresses that are not in local domains by doing a
DNS
# lookup on the domain name. Any domain that resolves to 0.0.0.0 or to a
# loopback interface address (127.0.0.0/Cool is treated as if it had no
DNS
# entry. Note that 0.0.0.0 is the same as 0.0.0.0/32, which is commonly
treated
# as the local host inside the network stack. It is not 0.0.0.0/0, the
default
# route. If the DNS lookup fails, no further routers are tried because
of
# the no_more setting, and consequently the address is unrouteable.
# The remaining routers handle addresses in the local domain(s).
# This router handles aliasing using a linearly searched alias file with
the
# name /etc/mail/aliases. When this configuration is installed
automatically,
# the name gets inserted into this file from whatever is set in Exim's
# build-time configuration. The default path is the traditional
/etc/aliases.
# If you install this configuration by hand, you need to specify the
correct
# path in the "data" setting below.
#
##### NB You must ensure that the alias file exists. It used to be the
case
##### NB that every Unix had that file, because it was the Sendmail
default.
##### NB These days, there are systems that don't have it. Your aliases
##### NB file should at least contain an alias for "postmaster".
#
# If any of your aliases expand to pipes or files, you will need to set
# up a user and a group for these deliveries to run under. You can do
# this by uncommenting the "user" option below (changing the user name
# as appropriate) and adding a "group" option if necessary.
Alternatively, you

# The no_verify setting means that this router is skipped when Exim is
