I now understood the RFC correctly. This little sentence I always overlooked: "If the string can be represented as a dot-atom (that is, it contains no characters other than atext characters or "." surrounded by atext characters),". So one dot surrounded by chars is ok, but not more dots in sequence or char-d...@. Cheers, Markus
