7/24 Sendmail/DNS question: If A has a MX 0 to B and B is MX 0 to itself and MX 10 to C, does A need an MX 10 to C or will mail to foo@A automagically go to C if B is down? \_ MXes don't chain; the target of an MX is a hostname, not another target for an MX lookup: ; domain file for http://bar.com mail IN MX 10 http://mail.foo.com. ; SMTP requires doing an MX lookup for http://bar.com, which will give it ; back http://mail.foo.com. it will _not_ do an MX lookup on http://mail.foo.com, ; merely an A record lookup (ordinary "name lookup") \- if there is not second MX for A -> C, then the mail will wait for B to come back. If there is a secondary MX for A -> C and B is down, I *believe* the answer is "it depends" ... you arent obligated to try another MX I think. Dont quote me on this. Recent sendmail should make one pass through them until one works or all of them are down, unless you get some exotic SMTP code which halts the whole process. If you are 100% sendmail see BAT II. If you have mixed agents, good luck reading the RFCs and sorting out the "musts" and "shoulds". This is subject to your not doing any of the weird things that turn off MX lookups. --psb |

Get it while you can. --dim \_ does that include stanford women? there is a stereotype they are too studious to date. \_ Did you mean "stupid" instead of "studious"? I've never met a stanford chick who had anything resembling a brain. Other parts were good, but just no intelligence. \_ Too ugly to care. See Clinton, Chelsea. --dim \_ Even those in biz school? \_ Get out from behind your computer screen more often, d00d. \_ D00D 570P TRY1NG 2 B3 '1337! After: ... \_ Definitely after.

7/25 read an article about some company up there which has developed an method to transfer high bandwidth using phone line- Actelis "Actelis overcame a longstanding problem of cross-talk, the interference caused by transmitting such vast amounts of data over copper wire with low capacity - interference that leads to high error rates in the data. "We get around this using spatial division multiplexing," says CEO Yuval Baron, explaining that the company has developed an algorithm that allows for error correction, letting high amounts of traffic to pass over copper wires without a problem." I was under the impression that the encoding wasn't the problem- it was the power required. The FCC has an upped limit on the amount of power which can be trasmitted over the phone lines- And from what I know Higher bandwidth means you need higher signal / noise means higher power going through the lines. This is the limiting factor involved with 56K modem how they such as the FCC doesn't let them go higher. They let the phone companies get away with DSL as those go through different switches- so what am I missing here? How sure how this company can make money in the long run given FCC regs, competition with DSL, compeition with cable, and Long haul capacity underutilized. thoughts comments.... \_ Hey, this was the first one that wasn't drivel. \_ no, it's still drivel. if someone else had posted a link to the story and made some coherent comments it might not have been. \_ wasn't the post signed by psb? and yes, it was total drivel and completely random question that didn't follow from the story. \_ i'm gonna keep putting drivel in motd.kinney even if it might be fake kinney. making fake drivel is pretty lame anyway so i'm gonna hope no one bothers. \_ Did we read the same post? The one I read was a question about transmission limits imposed on communications equip. by the FCC as it related to a new technology. It seems to be a non-drivel question. |
