Tomas,

  I have confirmed that it happens with or without mimedefang (in fact,=20
mimedefang was just being triggered on my incoming email account, and=20
not for the outgoing mail from squirrelmail)

I'm not sure what you mean by "vanilla squirrelmail package" as i=20
haven't done any modifications to the package (aside from miscellaneous=20
plugins) ... i've confirmed that this happens on two completely seperate=20
  installations of squirrelmail 1.4.3a-1

it looks like it's an encoding problem.
