Hello Guys,


My client has been getting the following message in OE, while sending
email:

---------------
The message could not be sent because one of the recipients was rejected
by the server. The rejected e-mail address was 'sales@???'. Subject
'hi', Account: 'SALES', Server: 'mail.example.net', Protocol: SMTP, Server
Response: '550 Administrative prohibition', Port: 25, Secure(SSL): No,
Server Error: 550, Error Number: 0x800CCC79"
---------------

The log shows this:

---------------
2005-07-03 23:10:16 no IP address found for host
adsl-156-1-178.bna.bellsouth.net (during SMTP connection from (EAGLE)
[70.156.1.178])
2005-07-03 23:10:16 H=(FALCON) [70.156.1.178] F=<sales@???>
rejected RCPT <sales@???>: host lookup failed for reverse lookup
check (70.156.1.178 does not match any IP address for
adsl-156-1-178.bna.bellsouth.net)
---------------

Another client is getting the same error '550 Administrative prohibition'
and his log shows this:

---------------
2005-07-05 12:50:56 H=(notebook-pc.2nd_example.com) [202.52.215.125]
F=<sales@2nd_example.com> rejected RCPT <info@customers_email.com>: host
lookup failed for reverse lookup check (failed to find host name from IP
address)
---------------

I checked both of the clients static IPs - assigned by their ISPs. The
first one has no 'A' record
defined in the PTR and the second one has no PTR. I think that is the
reason why they can not send
any emails. I'm using cPanel 10.2.0-C131 and CentOS 3.5 with EXIM 4.51 -
which is configured with
DCC, SPAMASSASSIN w/SARE (from http://rulesemporium.com/) & CLAMAV.

This issue can be resolved by un-checking the option "Verify the existence
of email senders" from
WHM by selecting the options of "Exim Configuration Editor".

I tried the following setup in - '/etc/exim.conf' and restarted exim:

     hostlist relay_hosts = lsearch;/etc/relayhosts : \
       localhost : 70.156.1.178 : 202.52.215.125


It didn't work. I was wondering if there are any other solutions to fix
this issue other than
un-checking the option: "Verify the existence of email senders". Or how can
I stop EXIM from checking
reverse IP lookup for these two IPs? My exim configuration is listed below
this email.

Thank you in advance for your cooperation...

#
# 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.

# rbl_domains = rbl.maps.vix.com


# 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
# to x%y@z (where z is one of your local domains) is locally rerouted to
# x@y and sent on. Otherwise x%y is treated as an ordinary local part.

# This director handles forwarding using traditional .forward files.
# If you want it also to allow mail filtering when a forward file
# starts with the string "# Exim filter", uncomment the "filter" option.
# The check_ancestor option means that if the forward file generates an
# address that is an ancestor of the current one, the current one gets
# passed on instead. This covers the case where A is aliased to B and B
# has a .forward file pointing to A. The three transports specified at the
# end are those that are used when forwarding generates a direct delivery
# to a file, or to a pipe, or sets up an auto-reply, respectively.
