But note that 0xF8 is illegal in UTF-8 (for several reasons), so most likely that is intended as an ISO 8-bit character. Do you agree that the interpretation of 0xF8 as "ø" is likely here?
I'm not sure. The mail body contains a signature "Nørregaard" in the plain text section and "N=C3=B8rregaard" in the HTML section, but there is no "ø" in the header (and thus nor the e-mail address of the subscriber).
This sounds like a bug in Mailman; if the headers do not contain any characters outside of ASCII, then for some reason Mailman (or the email module that it calls) is trying to decode the headers twice.
Can you provide a verbatim copy of the original message? (If privacy is a problem, send it to Mark Sapiro <mark@sapiro.net>. Mark is the likely person to actually do any fixing; I know how this stuff works in principle but haven't yet actually hacked the core code.) The whole thing, with no changes at all, please (you never know what matters in these things, even changing the .sig could make the bug go away!)
But even so, the fact that Mailman issued a 'new' command, the user should have been put on the list (i'm just speculating here, I'm not that familiar with e-mail handeling and especially not Mailman nor Python).
"Issue" a command and "complete" a command are two different things. I've already archived the earlier posts so I can't evaluate your conjecture offhand.
