hi,
i am missing the acl for smtp_auth. like this for example:
acl_smtp_auth = acl_check_auth
.
.
.
acl_check_auth:
accept condition = ${if
eq{${uc:$smtp_command_argument}}{PLAIN}{yes}{no}
deny message = PLAIN required
acl_check_auth_1:
accept condition = ${if
eq{${uc:$smtp_command_argument}}{LOGIN}{yes}{no}
deny message = LOGIN required
acl_check_auth_2:
accept condition = ${if
eq{${uc:$smtp_command_argument}}{CRAM-MD5}{yes}{no}
deny message = CRAM-MD5 required
.
.
.
begin authenticators
lookup_plain:
driver = plaintext
public_name = PLAIN
server_condition = ${if
eq{$3}{${lookup{$2}lsearch{/usr/local/exim/passwd}{$value}fail}}{yes}{no}}
server_set_id = $2
lookup_login:
driver = plaintext
public_name = LOGIN
server_prompts = Username:: : Password::
server_condition = ${if
eq{$2}{${lookup{$1}lsearch{/usr/local/exim/passwd}{$value}fail}}{yes}{no}}
server_set_id = $1
lookup_cram:
driver = cram_md5
public_name = CRAM-MD5
server_secret = ${if
eq{$2}{${lookup{$1}lsearch{/usr/local/exim/passwd}{$value}fail}}{yes}{no}}
server_set_id = $1

Betreff: [exim] SMTP authentication not working
Hi list
I am trying to setting up a mail server to allow users to send mail from any
IP as long as they can be authenticated. Been searching the archives and
have tried all sorts but I must be missing something. Below is my config
file. I'm trying to send an email through the server using outlook 2003
client.

# 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

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

# passing on to the next ACL statement (if tests above it fail) or denying

# 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.

Configuration file is /usr/local/exim/configure
Any clues why I keep getting "relay not permitted" in my server log. If I
modify to allow relay via IP it works just fine for my IP but not my
friend's IP, which is correct. I would also like to use TLS later, once the
basic authentication is working.
Thanks in advance
Mike
