ISP Information:
The British spelling of "fiber", i.e., "fibre" is used to describe this standard. Fibre Channel uses fiber-optic cable to connect computers or peripherals. It is much more expensive than standard copper cabling, and thus has been a niche product with lots of potential. Today it is used sparingly to connect RAID systems to computers, or to connect drives together within high-end RAID systems.

Fibre Channel - In article , Jeffrey Mattox wrote: The Mail Washer web site says : "... the bounced messages look exactly like a returned mail message you would receive if you sent an email off to a wrong address. There is no way the spammers can tell it is not genuine." But that is wrong! Spammers can tell because the bounce message comes as a delayed email (which they will ignore) rather than a refused connected by the SMTP protocol. With spammers using every trick they can to get emails through spam filters, why would anybody believe they would be fooled by a faked bounce message? Besides, spammers aren't interested in cleaning their lists. It's a waste of their time because it costs them nothing to keep the bad addresses. Damn them!I disagree. Mail often has to go through several hops before it gets tothe server that recognizes the mail account names. Also, many spammersmake use of open mail relays, they don't send directly to thedestination mail servers. For these reasons, they have no reason toexpect that the "No such user" error will occur during their SMTPdialog; many of the legitimate failures are delayed.You *are* correct that many spammers don't include a valid returnaddress, so the bounces will not go back to them in the first place.And you're also probably correct that they don't care about cleaning uptheir lists. Spam lists are valued by their size, not quality, eventhough spammers often advertise (in spam!) how clean their lists are.Barry Margolin, barmar@alum.mit.eduArlington, MA[TELECOM Digest Editor's Note: Barry is quite correct about how listsare valued by their size. I personally would rather have a small listof active, useful participants rather than a list of a million names99 percent of whom toss my stuff in the garbage each day. I think theydefine 'clean' to mean how much email sticks versus what bounces butpart of that problem is the number of netters who pitch it withouttaking the trouble to bounce it back. Spammers work by numbers and ifthere was a way to enforce valid return addresses on email and spam,and everyone who found it unwelcome did bounce it back, I suspect thespammers would be shocked by the volume of returned stuff they get,that they then had to dispose of, etc. Thats one reason I use the'bounce' feature in Mail Washer; hoping to God at least some of itgets back to the (true) originator to discourage them.
