The sendmail that I am using now (sendmail.4.0), doesn't seem to have this problem. [illustration of how the 4.0 version works] This is what senmdail.5.61 looks like in verbose mode with the same .cf file: edmund@cancun... Connecting to cancun.qualcomm.com (tcpld)... 220 qualcom.qualcomm.com Sendmail 5.61-bcr/1.34 ready at Tue, 6 Mar 90 10:01:12 -0800 >>> HELO qualcom.qualcomm.com 553 Local configuration error, hostname not recognized as local >>> QUIT 221 qualcom.qualcomm.com closing connection edmund@cancun... Service unavailable: Bad file number Saving message in /usr2/edmund/dead.letter /usr2/edmund/dead.letter... Sent The mailq is empty as well. Any ideas what it could be? OK - this is a CF file problem. Notice in the transaction above that your machine, qualcom, is trying to connect to itself to deliver mail to cancun. That's bad, because it means that qualcom has failed to realize that it *is* qualcom -- if Sendmail didn't pick this up, we would have a mail loop. Without knowing how your CF file is set up, it's tricky to know what's going on. Actually I take this back -- it seems, from your above script, that qualcomm thinks it's connecting to cancun, and that it's surprised when it winds up talking to itself. Could it be that the host information for your site is not entirely correct? I'll bet it's a /etc/hosts file vs. BIND discrepancy. I'll bet other mail goes through fine, right? Is it only mail for cancun which is weird, or is this a general phenomenon? -- Mark Towfigh, Racal Interlan, Inc. towfiq@interlan.Interlan.COM W: (508) 263-9929 H: (617) 488-2818 uunet!interlan!towfiq "The Earth is but One Country, and Mankind its Citizens" -- Baha'u'llah
