If I connect to sendmail from another machine on my (home) LAN, sendmail delays five seconds before sending the greeting. I would like it to respond immediately. A quick search turned up a "greet_delay" feature in sendmail that would cause this type of behavior. To the best of my knowledge, I do not use this feature. Just to be sure, I tried to explicitly enable it with both a default 0 second timeout and an explicit 0 second access rule. This did not the resolve the issue. I am at a loss. What could be going on?
