I caught Mail Server in the act this time. Below is a copy of a FidoNet Export file. Notice that the addressee line is MISSING THE "To:" IDENTIFIER!!! The lines with astricks denot the beginning and ending of the file, so you can see exactly what is there. The second message has the "To:" identifier. I do not know if all this whitespace (two blank lines) which appears at the beginning of the file is normal or correct for the MK gateway. I'll bet it is NOT because of the single line separating the first message fromthe seconf message.
