For those curious about the latency, I'm posting this at 12:08, on the US east coast. How long did it take to reach you?
I got it at 09:14, Pacific Daylight Time, so there appears to be no lag.
Here's the relevant headers for the bounceback to me, which took an hour:

I'm not sure which machine gets the blame, but it's either toad&uunet, or uunet&alcor.

sending mail to myself (not going through list processing), via toad.com, It took 32 seconds for my host to find, contact and send the mail to toad.com, then it took more than 5 minutes for it to come back, and specially it came back as : Received: from relay3.UU.NET by hplyot.obspm.fr with SMTP (1.36.108.10/16.2.5) id AA05486; Mon, 2 Oct 1995 19:48:39 +0100 Return-Path: <dl@hplyot.obspm.fr> Received: from toad.com by relay3.UU.NET with SMTP id QQzjtb16149; Mon, 2 Oct 1995 14:47:28 -0400 Received: from hplyot.obspm.fr by toad.com id AA02554; Mon, 2 Oct 95 11:42:59 PDT Received: by hplyot.obspm.fr (1.36.108.10/16.2.5) id AA05454; Mon, 2 Oct 1995 19:42:31 +0100 So the question now is : "Why the toad.com send its mail through *.uu.net instead of sending it directly ?" [it would/should cut at least by half the delay {at the coast of more DNS traffic for toad.com}] Also I suspect the long delays we sometime see comes from toad<->uu.net interactions [besides the normal overhead of sending one mail to thousands of people] (the service is great anyhow) dl -- Laurent Demailly * http://hplyot.obspm.fr/~dl/ * Linux|PGP|Gnu|Tcl|...
