You are saying your DNS server is getting these mails from other hosts like mercury1?
Assumed the DNS server is not the SMTP server, I suggest to stop the sendmail listener on the interfaces, in /etc/mail/sendmail.cf
Code:
O DaemonPortOptions=Addr=127.0.0.1, Name=MTA-v4, Family=inet
O DaemonPortOptions=Addr=127.0.0.1, Port=587, Name=MSA, M=E

And restart sendmail.
This will protect your server from further mails, and from DoS attacks on the sendmail port.
The /var/mail/mqueue will grow on the other (wrongly configured) hosts like mercury1.

ipa-server-install(1)						 IPA Manual Pages					     ipa-server-install(1)

NAME
ipa-server-install - Configure an IPA server SYNOPSIS
ipa-server-install [OPTION]... DESCRIPTION
Configures the services needed by an IPA server. This includes setting up a Kerberos Key Distribution Center (KDC) and a Kadmin daemon with an LDAP back-end, configuring Apache, configuring NTP and optionally configuring and starting an LDAP-backed DNS server. By default a dog- tag-based CA will be configured to issue server certificates. OPTIONS
BASIC OPTIONS -r REALM_NAME, --realm=REALM_NAME The Kerberos realm name for the IPA server. You will not be able to estabilish trust with Active Directory unless the realm name is uppercased domain name. -n DOMAIN_NAME, --domain=DOMAIN_NAME Your DNS domain name -p DM_PASSWORD, --ds-password=DM_PASSWORD The password to be used by the Directory Server for the Directory Manager user -P MASTER_PASSWORD, --master-password=MASTER_PASSWORD The kerberos master password (normally autogenerated) -a ADMIN_PASSWORD, --admin-password=ADMIN_PASSWORD The password for the IPA admin user --mkhomedir Create home directories for users on their first login --hostname=HOST_NAME The fully-qualified DNS name of this server. If the hostname does not match system hostname, the system hostname will be updated accordingly to prevent service failures. --ip-address=IP_ADDRESS The IP address of this server. If this address does not match the address the host resolves to and --setup-dns is not selected the installation will fail. If the server hostname is not resolvable, a record for the hostname and IP_ADDRESS is added to /etc/hosts. -N, --no-ntp Do not configure NTP --idstart=IDSTART The starting user and group id number (default random) --idmax=IDMAX The maximum user and group id number (default: idstart+199999). If set to zero, the default value will be used. --no_hbac_allow Don't install allow_all HBAC rule. This rule lets any user from any host access any service on any other host. It is expected that users will remove this rule before moving to production. --no-ui-redirect Do not automatically redirect to the Web UI. --ssh-trust-dns Configure OpenSSH client to trust DNS SSHFP records. --no-ssh Do not configure OpenSSH client. --no-sshd Do not configure OpenSSH server. -d, --debug Enable debug logging when more verbose output is needed -U, --unattended An unattended installation that will never prompt for user input CERTIFICATE SYSTEM OPTIONS --external-ca Generate a CSR to be signed by an external CA --external_cert_file=FILE PEM file containing a certificate signed by the external CA. Must be given with --external_ca_file. --external_ca_file=FILE PEM file containing the external CA chain --dirsrv_pkcs12=FILE PKCS#12 file containing the Directory Server SSL Certificate --http_pkcs12=FILE PKCS#12 file containing the Apache Server SSL Certificate --dirsrv_pin=DIRSRV_PIN The password of the Directory Server PKCS#12 file --http_pin=HTTP_PIN The password of the Apache Server PKCS#12 file --subject=SUBJECT The certificate subject base (default O=REALM.NAME) DNS OPTIONS --setup-dns Generate a DNS zone if it does not exist already and configure the DNS server. This option requires that you either specify at least one DNS forwarder through the --forwarder option or use the --no-forwarders option. Note that you can set up a DNS at any time after the initial IPA server install by running ipa-dns-install (see ipa-dns-install(1)). --forwarder=IP_ADDRESS Add a DNS forwarder to the DNS configuration. You can use this option multiple times to specify more forwarders, but at least one must be provided, unless the --no-forwarders option is specified. --no-forwarders Do not add any DNS forwarders. Root DNS servers will be used instead. --reverse-zone=REVERSE_ZONE The reverse DNS zone to use --no-reverse Do not create reverse DNS zone --zonemgr The e-mail address of the DNS zone manager. Defaults to hostmaster@DOMAIN --no-host-dns Do not use DNS for hostname lookup during installation --no-dns-sshfp Do not automatically create DNS SSHFP records. UNINSTALL OPTIONS --uninstall Uninstall an existing IPA installation -U, --unattended An unattended uninstallation that will never prompt for user input EXIT STATUS
