It seems that first Apache.org email message was a very thorough bug report for a bug that, alas, not only was already well documented, but which had already been fixed. The report was against Apache 1.3b3, which I mistakenly called 3.3b3. I guess, since 1.3 hadn’t released yet, that we must have been running 1.2 at the time at DataBeam.
That was in January of 1998, though, and I am pretty sure that I had already been running Apache for at least 2 years by then, and NCSA before that. It seems strange that I never sent a message to a mailing list before then.
