Fraser,
OK, I've determined that there are at least *three* bugs all interacting in
tandem to cause the problem we are seeing:
1. I have a bug in my article-posting script: Whenever you have the
"Please e-mail me a copy of my message" option checked, the email
portion of the article-posting script -- which runs after the portion
which posts the article to the newsserver -- uses the email address you
gave (which may contain a spamblock), rather than your true email
address. In other words, it was trying to send mail to
fraser@<nospam>lovatt.com
which isn't valid in the eyes of the mail transfer agent because < and >
have special meanings in email address syntax. (I verified that the MTA
gacks on this this by sending a foofoo message to that address and
seeing the error.) Since your real email address (the above minus the
<nospam> part) was known at the time your article was submitted, this is
where the email should have been directed. That's the first bug.
2. I have a second bug in my article-posting script: The call to the mail
transfer agent doesn't handle STDOUT and STDERR properly when the MTA
reports errors; it's just letting it float through back to the webserver
as part of the page. So the child process is writing
fraser@<nospam>lovatt.com... User unknown
to STDOUT before the parent process writes any of the HTTP response
headers. Hence the 500-error (Internal Server Error). Your article
gets posted just fine, but the webserver garbles up the response page.
That's the second bug.
3. Your version of MSIE has a bug: It is submitting your HTML form
contents twice -- about 3 seconds apart. Apparently it doesn't like
receiving the 500-error and freaks out. But regardless of what it
thinks about the 500-error, it definitely shouldn't be submitting the
form a second time without asking you. That's the third bug.
Obviously I can't fix bug #3, but I can and will certainly eliminate my two
bugs which drew #3 into the limelight. Fixing #1 and #2 will make #3
disappear without fixing #3.
BTW, since fixing bug #1 would conceal bug #2 in this case, I'm going to fix
bug #2 first, making sure it holds up in light of bug #1, then fix bug #1.
Could you post another test message to the .off-topic.test group (making
sure the "Please e-mail me a copy of my message" option is still checked),
and let me know if you still get the 500-error? Then I'll go back and fix
the other bug.
Thanks for your help!
