Okay to end all the speculation what's wrong with Esther's mails:
Nothing. They were just fine, but it looks like the mailinglist
software caused a problem... let's look at the source of one of Esther's
mails (showing only relevant things):

As you can see, the whole mailbody is Base64 encoded, which is perfectly
okay to ensure the UTF-8 stuff goes through correctly. The problem is
caused by the signature added by the mailinglist software. It is just
appended to the mailbody, ignoring the fact that the body is Base64.
We now have a block which is partly base64 and partly plain ASCII - what
happens with such a mail depends heavyly on the receiving mail client.
Sylpheed just ignores the parts that are not valid Base64, Cone tries to
decode the not encoded part, producing garbage. Other Clients will throw
away the whole body as invalid.
So Esther's mails were fine - it seems to be the mailinglist software that
is broken (or maybe I misconfigured something). I will CC this mail to
the John Madden (the freelists admin) maybe he can fix that.
