You should get a copy of RFC886, "Proposed Standard for Message Header Munging". This RFC is dated December 1983 and I have not heard or seen any updates to it so this should be the latest "proposed standard". Having read this document a few times it is still not clear how to answer your question. But my gut feeling is that "a!b%c" should be rewritten as "a@b" or perhaps "@c:a@b", or maybe even "b@c" .... :-) Other RFCs that may be of interest are: RFC822 - Standard for the Format of ARPA Internet Text Messages RFC974 - Mail Routing and the Domain System RFC976 - UUCP Mail Interchange Format Standard --Dan Ehrlich Dan Ehrlich The Pennsylvania State University, Department of Computer Science 333 Whitmore Laboratory, University Park, PA 16802 +1 814 863 1142 or +1 814 865 9723
