I get the following message from my sendmail, which indicates that it is trying to connect to itself. >>> HELO seismo.gps.caltech.edu <<< 553 Local configuration error, hostname not recognized as local 554 ... Service unavailable 1. Is this my problem or the problem of the sender? It looks like the rulesets that should be parsing this incoming address are: 3, 0 The following comment in my ruleset 0 that appears to indicate that it is the job of the SENDER to resolve this address to a hostname. ( I don't know who is responsible for the comments:) # For numeric spec, you can't pass spec on to receiver, since rcvr's # are not smart enough to know that [x.y.z.a] is their own name. 2. If it IS my problem, how should I handle it? What rules can I use to resolve an internet address into a hostname (so that it can recognize that it is its own address) without hard-wiring my internet address(es) into it? -- ---------------------------------------------------------------------------- Doug Neuhauser Div. of Geological and Planetary Sciences doug@seismo.gps.caltech.edu California Institute of Technology 818-356-3993 MS 252-21, Pasadena, CA 91125
