I was originally planning to propose to remove any comparison with FTP,
possibly creating another draft (Chris Newman wrote one in 1998) that
would compare reply codes from different protocols. However after
checking -03, I only found the following paragraph:
rfc2821bis-03 adds new text to explicitly compare SMTP's reply
code model to that of FTP in the hope of eliminating any
possible residual confusion about issues 18 and 28. Should that
text be retained, dropped, or modified in some way?
It is worth noting that the file transfer protocol (FTP ) uses a
very similar code architecture and that the SMTP codes are based on
the FTP model. However, SMTP uses a one-command, one-response model,
while FTP is asynchronous and the 1yz codes are not part of the SMTP
I think this is a reasonable text and it is small. I think it should be
kept as is.
