This machine handles mail for over 60 domains, and we're starting to get complaints from customers. What is happening is that MUAs (Outlook, Netscape, Pine) connecting to sendmail to send mail experience a 10-30 second delay before the message is sent. I've double- and triple-checked that all DNS related services are working properly on this box. As a test, I tried connecting to port 25 and 587 via localhost and by external IP from the box itself. In both of these tests, the sendmail banner comes up immediately. However, connecting from a remote box does this: gabby# telnet mydomain.com 25 Trying A.B.C.D... telnet: connect to address A.B.C.D: Network dropped connection on reset telnet: Unable to connect to remote host gabby# However, if I connect via the "submission port" (587), a connection comes up immediately. This explains why we're not seeing any delays in mail propagation, since the MTAs (using port 587) are getting connected immediately. However, sending mail from MUAs (which use port 25) are seeing delays. Does any one have any ideas on how to fix this? -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
