fdnsmxalist(1) General Commands Manual fdnsmxalist(1)NAMEfdnsmxalist - resolve a list of MX records and their corresponding A records for hostnameSYNOPSISfdnsmxalist [-x] <hostname>DESCRIPTIONfdnsmxalist will attempt to look up a list of MX records for hostname. If any are found, they are printed to standard output seperated by newlines in the format: Protocol (Priority) hostname:port The program then looks up lists of A and AAAA records for each MX record, and prints them to standard output, one IP per line. Lines are printed to standard output starting with "ERROR: " if any MX records have no corresponding A or AAAA records, are CNAMEs (an RFC viola- tion), or have A or AAAA records which point to non-routable IP addresses. If the -x switch is passed on the command line, the program outputs machine-parsable XML instead of the human-readable tree. Exit codes for the program are: 0 - Everything looks fine 1 - An MX has a non-routable IP 2 - An MX doesn't exist 3 - An MX is a CNAME 4 - An MX is an IP address 100 - Invalid syntax 103 - DNS timeout or host does not have MX recordsAUTHORIan Gulliver <ian@penguinhosting.net>SEE ALSOlibfiredns(3) 2004-02-12 fdnsmxalist(1)
