This is a public thank you to Robert on the Foundations Support Line in Canada and to Matt Webb at IBM in Australia for helping me with my current support issue. Matt has been researching this problem in his own time (and I've got the time-stamped emails to prove it!) and together with long distance support from Robert we have almost beaten the problem.
The problem was that a customer's Foundations server suddenly stopped accepting SMTP mail. The Domino SMTP task was active and internal<->internal mail was being delivered as was internal->external mail. That server had been running fine for a couple of months and it was a complete mystery as to what had caused the problem. In the end we told the server to run a Netscan command to automatically detect its network connections and rebuild its internet access routes.
So that's what it did.
Maybe I impress too easy but I found that to be quite an elegant piece of autonomic computing. I wish organizing my personal finances was that easy. "OK Tax Return! It's the end of the Financial Year. Go away and inspect my accounting environment and fill in your blanks then tell me when you're ready to be sent to the Tax Office."
The original issue isn't completely resolved yet since the customer has switched their mail to another email server for the duration. Now we need to switch it back and run some mail-delivery tests but I think we're on the Home Stretch.
Anyway, I want to give public recognition and thanks where it's due.
Thanks again Matt and Robert. I hope your Managers read this.
