Resources and their uses can be -- and often are -- a long way away and using connections with wildly varied performance characteristics. But we talk about 300 sec vs. 30 sec timeout for **TLS handshake**. That is why I was careful not to argue against timeouts, per se, but merely not to consider expected distance as a factor. There are a number of reasons for needing timeouts. And the choice of how long or short one should be often is operationally subjective. Just don't make an assumption about the distance between user and server as part of the analysis. Anyway, i understand original suggestion not as distance in meters, but as distance to contact... And that distance is definitelly different for SMTP and for Submission(S). I mean distance in any terms at all. Don't assume the user is distant or close in miles or fast or slow in response time. Or high or low in bandwidth. One of the serious problems with having excellent, high performance, highly reliable connections for so many of us, for so much of the time, is that it leads to designers and admins thinking that that operational reality applies to everyone, all the time. It doesn't. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net mast:@dcrocker@mastodon.social Links: ------ [1] mailto:mailop@mailop.org
