The return address you should have had was "[email protected]". baylink.com MX's to scfn.thpl.lib.fl.us, which is an A record. $ ns -q=any baylink.com Server: ns1.thpl.lib.fl.us Address: 204.198.80.2 baylink.com origin = ns1.thpl.lib.fl.us mail addr = jra.scfn.thpl.lib.fl.us serial = 960502 refresh = 3600 (1 hour) retry = 300 (5 mins) expire = 3600000 (41 days 16 hours) minimum ttl = 3600 (1 hour) baylink.com nameserver = ns1.thpl.lib.fl.us baylink.com CPU = SPARCstation 20/51 OS = SunOS 4.1.3_U1 baylink.com mailbox = jra.scfn.thpl.lib.fl.us text = contact.baylink.com baylink.com preference = 1, mail exchanger = scfn.thpl.lib.fl.us baylink.com nameserver = ns1.thpl.lib.fl.us ns1.thpl.lib.fl.us internet address = 204.198.80.2 scfn.thpl.lib.fl.us internet address = 204.198.80.3 Apologies to the NANOG list, but until Greg makes his mailer a littl less (incorrectly) anal-retentive, he otherwise won't see this... and I'd hate for an ops guy not to know that his gear is configured wrong. :-) Cheers, -- jra -- Jay R.
