I am, as mentioned in an earlier posting, writing
an SMTP server for our Xerox Dandelions. Many
people helped me with my initial query and I hope
someone can clarify one specific point.
When I receive a message, the SMTP envelope has a
RCPT TO:<mailbox> line. In addition, the letter has
a header field To: mailbox. Do I need to look at
both? Should I ignore the lines in the letter's
822 header when delivering the letter? (This would
be easier than trying to parse the whole thing.)

Period. The message text (header) itself is then checked for a To: field and if none if found, an Apparently-to: field is created and filled in with what was passed to RCPT TO: Likewise, the message text itself is scanned for a From: field and if none is found, an Appanrently-From: field is created and filled in with what was passed to RCPT To: (Kevin- I'll send you messages over ARPA demonstrating this when I get a chance) -Eric Starkman
