There's also the 251 reply code. That's for address correction.
I was thinking about something like (nor 4xx nor 5xx) :
303 FORWARD somepath(_at_)domain(_dot_)com
You can get the same functionality with a 251 reply code where the
MTA accepts the message and forwards it to the new address. It's a
redirection in the sense that the MTA is doing an address rewrite and
relaying or delivering the message to the new mailbox.
There is no need for a new reply code if the text after the reply
code is structured. You still have to determine how to relay the new
address back to the MUA as SMTP does hop by hop delivery. HTTP, on
the other hand, requires a direct connection between the server and
the user agent. Even if there is a proxy in the middle, the user
agent still has access to the HTTP reply code.
