testmxlookup
TESTMXLOOKUP(1) Double Precision, Inc. TESTMXLOOKUP(1)
NAME
testmxlookup - Look up mail relays for a domain
SYNOPSIS
testmxlookup [@ip-address] [--dnssec] [--udpsize n] {domain}
DESCRIPTION
testmxlookup lists the names and IP addresses of mail relays that receive mail for the domain. This is useful in diagnosing mail delivery
problems.
testmxlookup sends a DNS MX query for the specified domain, followed by A/AAAA queries, if needed. testmxlookup lists the hostname and the
IP address of every mail relay, and its MX priority.
DIAGNOSTICS
The error message "Hard error" indicates that the domain does not exist, or does not have any mail relays. The error message "Soft error"
indicates a temporary error condition (usually a network failure of some sorts, or the local DNS server is down).
OPTIONS
@ip-address
Specify the DNS server's IP address, where to send the DNS query to, overriding the default DNS server addresses read from
/etc/resolv.conf.
"ip-address" must be a literal, numeric, IP address.
--dnssec
Enable the DNSSEC extension. If the DNS server has DNSSEC enabled, and the specified domain's DNS records are signed, the list of IP
addresses is suffixed by "(DNSSEC)", indicating a signed response.
This is a diagnostic option. Older DNS servers may respond with an error, to a DNSSEC query.
--udpsize n
Specify that n is the largest UDP packet size that the DNS server may send. This option is only valid together with "--dnssec". If
"--dnssec" always returns an error, try "--udpsize 512" (the default setting is 1280 bytes, which is adequate for Ethernet, but other
kinds of networks may impose lower limits).
