Created attachment 1116 [details] gzipped email shows a message having the munging problem A recent email I received has the following character sequence in it: fmxRedirect.pl?id=ABZbLgc Claws-Mail rendered it as: fmxRedirect.pl?id
it's a broken mail. It claims to be ISO-8859-1 when it's UTF-8 and, more importantly, it claims to use quoted-printable encoding, but it's not actually using it. It's this latter point that causes the link to break at the = symbol.
