The author (so to say) of that strange check is RFC 2822 - Internet
Message Format.

    2.1.1. Line Length Limits

        There are two limits that this standard places on the number of
        characters in a line. Each line of characters MUST be no more
        than 998 characters, and SHOULD be no more than 78 characters,
        excluding the CRLF.

        The 998 character limit is due to limitations in many
        implementations which send, receive, or store Internet Message
        Format messages that simply cannot handle more than 998
        characters on a line. [...]

Perhaps longer lines will work in many cases but atleast warning should
be printed to user, or something.
