Re: improper restart after RSET?

["Mariano Absatz" <zmailer@lists.com.ar>]

The Right Thing (TM) is to wait for a "MAIL FROM:" (not a HELO/EHLO), from 
RFC2822:

4.1.1.5 RESET (RSET)

   This command specifies that the current mail transaction will be
   aborted.  Any stored sender, recipients, and mail data MUST be
   discarded, and all buffers and state tables cleared.  The receiver
   MUST send a "250 OK" reply to a RSET command with no arguments.  A
   reset command may be issued by the client at any time.  It is
   effectively equivalent to a NOOP (i.e., if has no effect) if issued
   immediately after EHLO, before EHLO is issued in the session, after
   an end-of-data indicator has been sent and acknowledged, or
   immediately before a QUIT.  An SMTP server MUST NOT close the
   connection as the result of receiving a RSET; that action is reserved
   for QUIT (see section 4.1.1.10).
