Actually RFC 2821 clarifies this pretty specifically despite
the
"controversy" over it.  None the less that debate
is not of concern to me
but the software I was (am) testing is. (I'm testing
Spiceworks from
http://www.spiceworks.com)

Specifically it states:
---Paste---
3.6 Domains

   Only resolvable, fully-qualified, domain names (FQDNs)
are permitted
   when domain names are used in SMTP.  In other words,
names that can
   be resolved to MX RRs or A RRs (as discussed in section
5) are
   permitted, as are CNAME RRs whose targets can be
resolved, in turn,
   to MX or A RRs.  Local nicknames or unqualified names
MUST NOT be
   used.  There are two exceptions to the rule requiring
FQDNs:

   -  The domain name given in the EHLO command MUST BE
either a primary
      host name (a domain name that resolves to an A RR) or,
if the host
      has no name, an address literal as described in
section 4.1.1.1.

   -  The reserved mailbox name "postmaster" may
be used in a RCPT
      command without domain qualification (see section
4.1.1.3) and
      MUST be accepted if so used.

For best results, the name specified in the helo or ehlo
command should resolve to the IP address of the host
originating the connection. Some mail servers have strict
filters in this regard and will not accept mail otherwise.
