Well, not quite 42 hours. That's not "several days" in my book.

Yes, I care. > My message to Greg Lehey was rejected by his mail server, Well, there's something that you can fix in the meantime :-) > but I am pretty sure he reads both -hackers and -stable. Correct. I also have other things to do. When you sent the backtrace, I was away from home doing some training, and I didn't have access to my machines. I'll look at it, but it would be *really* nice if you'd give me the info I ask for.

Correct. There's nothing wrong with your stripe size. I suspect you took it from one of the valid examples in the man page. >>> Does anyone care?

It was in the reject message. You apparently chose to ignore it. You've made me go and look in the logs: Sep 14 10:58:46 wantadilla postfix/smtpd[17429]: reject: RCPT from ewey-rwcmta.excite.com[198.3.99.191]: 550 <john_wilson100@excite.com>: Sender address rejected: " Mail rejected.
