     SMTP 521 and 556 Reply Codes

Summary: This document is ready for publication as a Proposed Standard.

Major issues:

Minor issues:
     The description of the 556 reply code in section 4 seems to switch 
between refering to the generating entity as a client and as a sesrver. 
  I presume this is because the actual sitaution is an SMTP server is 
trying to pass information onwards, and in that onwards direction it is 
a client which.  But it is still confusing for an SMTP client to make a 
determination and then an SMTP server which is apparently the same 
entity to generate the rror code to some other SMPT client.
