temporarily rejected RCPT : lowest numbered MX record points to local host

This indicates that the domain doesn’t exist in /etc/localdomains. Edit the file with your favorite editor and ensure it’s listed there.

At the same time, you’ll want to ensure it isn’t listed in /etc/remotedomains.

You’ll want to create a file called /scripts/postwwwacct, and add the following content:

my %OPTS = @ARGV;
my $user = $OPTS{’user’};
/usr/local/cpanel/bin/domain_keys_installer $user

You’re all set now — there’s nothing else that needs to be done. Note that this only creates the DomainKeys records for new accounts. If you want to create DomainKeys records for all your existing users at once, check out my other article on the topic: http://www.cpaneladmins.com/2009/12/07/install-domainkeys-and-spf-records-for-all-users/

We're sorry, we hit a bug!

Let’s make sure that all other permissions are set properly:

# ./usr/local/cpanel/3rdparty/mailman/bin/check_perms
No problems found

As mailman is working properly on this server, no errors were discovered, but as you’re received the error above, you’ll likely see some errors displayed.

SPF Record Check – via HTTP
PoliteMail’s SPF Check – outputs a brief breakdown of your records details – the IP addresses permitted in the record, the hostname, and the mailserver name. Then outputs the TXT record it queried.

MXToolBox’s SuperTool – Provides SPF checks, among other useful queries.

SPF Record Check – via email
This is pretty neat – you can send an email to spf-test@openspf.org from the domain you want to test, and it will reject the message, but in that rejection message, you’ll see the results of your test:

spf-test@openspf.org
SMTP error from remote mail server after RCPT TO::
host mailout02.controlledmail.com [72.81.252.18]:
550 5.7.1 : Recipient address rejected:
SPF Tests: Mail-From Result="pass": Mail From="test@cpaneladmins.com" HELO name="server.cpaneladmins.com" HELO Result="none" Remote IP="12.34.56.78"

input type="text" name="quota" value="250"


Change the value from 250 to your new default. This will modify the default quota server-wide.

In WHM, go to Exim Configuration Editor, then select Advanced Editor. In the first field, paste in:


log_selector = +address_rewrite +all_parents +arguments +connection_reject +delay_delivery +delivery_size +dnslist_defer +incoming_interface +incoming_port +lost_incoming_connection +queue_run +received_sender +received_recipients +retry_defer +sender_on_delivery +size_reject +skip_delivery +smtp_confirmation +smtp_connection +smtp_protocol_error +smtp_syntax_error +subject


You will then see extended logging in /var/log/exim_mainlog. You can simply run

grep cwd=/home /var/log/exim_mainlog

and that will show you the path for any user that is sending email via sendmail through exim. It won’t give you the filename, but at least you’ll have the user/folder name, and you can look through the scripts from there.
