It sure is. Thank you very much Albrecht- I appreciate you compiling  
this info for me. Only one worry, though- signatures(the human readable  
kind) are usually prepended with a "-- \n" - note the trailing  
whitespace. I've seen it discussed many a time that mailers incorrectly  
gobble the trailing whitespace, as this is a standard that some MUAs  
depend on to, say, display the .sig in a different color. Is this the  
case here with two conflicting standards, as the RFC states that  
trailing whitespaces should be ignored?
