I received an email with a x-ms-exchange-antispam-messagedata-0: header and I tried to forward it with kmail.
That caused error message: "The server said: maximum allowed line length is 998 octets, got 1702" In the original message, the header was split into multiple lines like this: x-ms-exchange-antispam-messagedata-0: =?iso-8859-1?Q?X9nvzr27qYcmEJpSHcp6K5gWYoBjPRlTmpppdR4VrmwY1cP0Mp4QNB9+kY?= =?iso-8859-1?Q?ZWd5EsMdHUa4x0pKA1ObLVns8RuLFV3mCsHlMT31xBfLxra6jZ+p5hbSHx?= But when the message was forwarded with kmail, the header turned into one too long line: x-ms-exchange-antispam-messagedata-0: lwf7pdVSQS1T... It seems that kmail has more than one header "fixing" problem.
