Additionally Adding a vcard (generated via kmail which inserts \r\n as per spec IIRC). There may also be an issue with either kmail or MS exchange (though I doubt MS would want to remove it's precious carriage return character) replacing \r with \n resulting in \n\n substitution for \r\n, and hence voiding the digest again. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ Kdepim-bugs mailing list Kdepim-bugs@kde.org https://mail.kde.org/mailman/listinfo/kdepim-bugs
