SuSE Linux Enterprise Server 9
Postfix 2.1.1


Error: "Jul 10 09:03:44 server postfix/smtp[28973]: 6CF624C6E:
to=, relay=none, delay=0, status=bounced (Host or domain name not
found. Name service error for type=AAAA: Host found but no data record of requested type)"
Error: "
Name service error for type=A: Host found but no data record of requested type)"
Relayhost defined in /etc/postfix/
Mail not getting sent to relay host


There are various allowed formats for the relayhost directive:
# The relayhost parameter specifies the default host to send mail to
# when no entry is matched in the optional transport(5) table. When
# no relayhost is given, mail is routed directly to the destination.
# On an intranet, specify the organizational domain name. If your
# internal DNS uses no MX records, specify the name of the intranet
# gateway host instead.
# In the case of SMTP, specify a domain, host, host:port, [host]:port,
# [address] or [address]:port; the form [host] turns off MX lookups.
# If you're connected via UUCP, see also the default_transport parameter.
#relayhost = $mydomain
#relayhost = []
#relayhost = [mailserver.isp.tld]
#relayhost = uucphost
#relayhost = [an.ip.add.ress]

The format that worked is:
relayhost =
