I have to agree that SMTP is pretty solid...I ran mailservice (MTAs) on 15 Unix servers between 1991 and 1996 and the mailqueues got their tails tangles up about once a week but since I monitored the queues, I generally fixed the problem within 1 or 2 queue cycles (queues ran every 15 minutes). Newer Unix and Open Source MTAs are much better but I don't get the same feeling about MS Exchange MTAs.
My point has always been something like this example... Nameservers TLD6.ULTRADNS.CO.UK, TLD1.ULTRADNS.CO.NET, TLD2.ULTRADNS.CO.NET, TLD3.ULTRADNS.CO.org, TLD4.ULTRADNS.CO.org, TLD5.ULTRADNS.CO.INFO and mail.jnos.org get hacked/bombed/etc. So I can't sent to [EMAIL PROTECTED] But lets assume its usa.redcross.org and mail.redcross.org (both are 162.6.217.63) and mail.redcross.org.edgekey.net are hacked/bombed, etc. Would this cause a problem in a disaster relief situation? That about failure of damascus.sarmy.org, baracuda.sarmy.org, fallback.mail.uk.uu.net, www.sarmy.org or TLD6.ULTRADNS.CO.UK, TLD1.ULTRADNS.CO.NET, TLD2.ULTRADNS.CO.NET, TLD3.ULTRADNS.CO.org, TLD4.ULTRADNS.CO.org, TLD5.ULTRADNS.CO.INFO? Notice a common thread here...the Red Cross and Salvation Army are using the same name servers. Ok...so it doesn't really matter how robust SMTP is or isn't, its still a problem if key parts of the Internet fail that support certain and specific "elements" in emergency or disaster relief communications. What is these organization's fall back? And, how well can amateur radio assist them in their need for messaging?

Maybe in the future there will be yet another protocol for > sending email that IS reliable and guaranteed delivery, but SMTP isn't it! Lets make a little wager. I'll guarantee this message gets to the list using the supposedly unreliable SMTP technology. I'll guarantee it for X dollars that it works. Now - for what value of Y dollars will anybody here guarantee me that it doesn't work? Do we lose one message in a hundred? A thousand? It's all statistics... Now who'd like to take the same odds on the same number and same size NTS messages? CW? SMTP isn't perfect, but it's pretty incredible -- specially if all the backup mechanisms (MX records and SMTP gateways) are correctly set up. If anybody is still reading these rants, here's a digital radio question. I saw an Amateur Radio booth at a state fair yesterday. Very well done and I was very impressed. But - they had a code key up front and a fancy Icom 756 Pro radio next to a computer monitor with a simple web page. Wouldn't a Ham Radio Deluxe or similar program on 14.070 have made an impressive display? Is there a better wizzy program? 73 Bill - WA7NWP Need a Digital mode QSO?
