The main symptom is that Postfix cannot deliver mail:
[...] (Host or domain name not found. Name service error for name=egg-mail.egps.com type=A: Host not found, try again)
but dig works:
# dig egg-mail.egps.com
[...]
;; ANSWER SECTION:
egg-mail.egps.com. 86400 IN A 10.1.1.84
unless I try trace:
# dig +trace egps.com
[root server stuff snipped]
dig: isc_socket_create: address family not supported
and ssh fails:
# ssh root@salami.egps.com
ssh: Could not resolve hostname salami.egps.com:
Temporary failure in name resolution
Eh?
