I assume you are telnet'ing from the Postfix server with the queue delay problem. At this point, after you receive the 220, type: ehlo your.postfix-server.tld <enter> and time the delay of the 250 responses. Continue to do a complete manual mail transaction through telnet, and time each smtp command completion (wall clock is fine). Post the results here please. -- Stan
