Version: (using KDE KDE 3.5.8) Installed from: Ubuntu Packages The word wrapping in kmail is limited to 78 charactes, but the upper limit should be 998 characters. It is often claimed that RFC822 would forbid lines longer than 78 characters + CRLF. Actually I cannot find any restriction there (http://tools.ietf.org/html/rfc822). RFC822 has been obsoleted by RFC2822 anyway and RFC2822 allows lines of up to 998 characters. That is more than the total characters in many mails. (http://tools.ietf.org/html/rfc2822) (BTW: Along with this it would be helpful to have http://bugs.kde.org/show_bug.cgi?id=31951 (from 2001) fixed as well.)
Confirm that this restriction still exists on KDE 4.2.2 although the upper limit now appears to be 255 (Configure>Kmail>Composer>Word Wrap).
