Subject: [exim] 550 relay not permitted from Outlook
Hi,

I don't know why I can't send email from Outlook to external mail server.
Here is the error:

2004-11-06 23:34:03 H=winserv.mydom.com (winserver) [192.168.9.1]
F=<bob@???> rejected RCPT <jen@???>: All acls are failed -
relay not permitted

mydom.com is the domain name of the Exim mail server. telstra.com is an
external mail server.
bob@??? is trying to send email from another side of the Internet
thru my Exim mail server mydom.com to external mail server telstra.com.

The problem is if bob send this with Mozilla, it works fine with
authentication cram-md5. I don't understand why mozilla can use cram-md5
on smtp auth, but Outlook failed with error 550 relay not permitted.

I m not sure whether exim/configure file missing something in the ACLs
section.
Here is the ACL section in my exim/configure file:

######################################################################
#                       ACL CONFIGURATION                            #
#         Specifies access control lists for incoming SMTP mail      #
######################################################################


begin acl

# This access control list is used for every RCPT command in an incoming
# SMTP message. The tests are run in order until the address is either
# accepted or denied.

acl_check_rcpt:
accept domains = +local_domains
accept hosts = +relay_hosts

# Accept if the source is local SMTP (i.e. not over TCP/IP). We do this by
# testing for an empty sending host field.

accept hosts = :


#############################################################################
# The following section of the ACL is concerned with local parts that
contain
# @ or % or ! or / or | or dots in unusual places.
#
# The 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 lock them
# out, 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
# someone like me, who has no 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.
#
# Two different rules are used. The first one is stricter, and is
applied to
# messages that are addressed to one of the local domains handled by this
# host. It blocks local parts that begin with a dot or contain @ % ! /
or |.
# If you have local accounts that include these characters, you will
have to
# modify this rule.

  deny    message       = Restricted characters in address
          domains       = +local_domains
          local_parts   = ^[.] : ^.*[@%!/|]


# The second rule applies to all other domains, and is less strict. This
# allows your own 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 @ % and
! is
# blocked, as before. The motivation here is to prevent your users (or
# your users' viruses) from mounting certain kinds of attack on remote
sites.

  deny    message       = Restricted characters in address
          domains       = !+local_domains
          local_parts   = ^[./|] : ^.*[@%!] : ^.*/\\.\\./


#############################################################################

# Accept mail to postmaster in any local domain, regardless of the source,
# and without verifying the sender.

  accept  local_parts   = postmaster
          domains       = +local_domains


# Deny unless the sender address can be verified.

  require verify        = sender



#############################################################################
  # There are no checks on DNS "black" lists because the domains that 
contain
  # these lists are changing all the time. However, here are two examples of
  # how you could get Exim to perform a DNS black list lookup at this point.
  # The first one denies, while the second just warns.
  #
  # deny    message       = rejected because $sender_host_address is in 
a black list at $dnslist_domain\n$dnslist_text
  #         dnslists      = black.list.example
  #
  # warn    message       = X-Warning: $sender_host_address is in a 
black list at $dnslist_domain
  #         log_message   = found in $dnslist_domain
  #         dnslists      = black.list.example


#############################################################################

# Accept if the address is in a local domain, but only if the
recipient can
# be verified. Otherwise deny. The "endpass" line is the border between
# passing on to the next ACL statement (if tests above it fail) or denying
# access (if tests below it fail).

  accept  domains       = +local_domains
          endpass
          verify        = recipient


  # Accept if the address is in a domain for which we are relaying, but 
again,
  # only if the recipient can be verified.
  accept  domains       = +relay_to_domains
          endpass
          verify        = recipient


# If control reaches this point, the domain is neither in +local_domains
# nor in +relay_to_domains.

# Accept if the message comes from one of the hosts for which we are an
# outgoing relay. Recipient verification is omitted here, because in many
# cases the clients are dumb MUAs that don't cope well with SMTP error
# responses. If you are actually relaying out from MTAs, you should
probably
# add recipient verification here.

  accept  hosts         = +relay_from_hosts


# Accept if the message arrived over an authenticated connection, from
# any host. Again, these messages are usually from MUAs, so recipient
# verification is omitted.

accept authenticated = *

# Reaching the end of the ACL causes a "deny", but we might as well give
# an explicit message.

  deny    message       = All acls are failed - relay not permitted



Thanks
